Hydroacoustic complexes pl in anti-submarine struggle
The diesel-electric boats of the first post-war projects "paved the road" for the crews of modern submarines, in the ocean campaigns, gaining operation of operation of military equipment, mastering the techniques of treated swimming, studying the hydrological and hydrographic situation of strategically important areas of the ocean, practicing the tactics of anti-palmary and anti-worr.
The tactics of anti-submarine struggle is often reduced to the search and detection of the Eagle PL using hydroacoustic means earlier than the enemy does.
At the same time, the state of the surrounding medium acquires the most important value, especially such parameters, as the zones of acoustic convergence and the position of the submarine relative to the "thermocline".
The convergence zones are ring-shaped areas around the underwater ship. The sound heading down from the convergence point located in the convergence zone is refracted depending on the pressure and temperature of the water, moves up and down with respect to the surface of the spiral through irregular intervals, which also depend on the state of the surrounding environment.
The commander of the ship, trying not to fall into these areas - as to where, in his opinion, the goal is, it can avoid detection. To do this, he needs to be within the areas where the sound applies to its source is simply radially.
The easiest way is to take a position above the layer of temperature jump (thermocline) or under it so that it shares the submarines - then the sounds published by its engine will most likely be reflected from the layer and the enemy boat will not detect it.
Temperature leap is a borderline layer of underwater space, separating warm superficial water and colder profound areas.
Diesel submarines Along with atomic, they occupy a prominent place in the aggressive plans of the NATO Block of the NATO countries. According to the reference book "Jane", in mid-1980, in the fleets of the North Atlantic Union, there were 186 diesel boats.
Diesel submarines have certain advantages of atomic, they are related, in particular, less noise, which improves the conditions for the operation of hydroacoustic stations (GAS) when solving the problems of anti-submarine struggle.
Currently, according to foreign press, the integration of hydroacoustic technology with Bius and weapon management systems occurring on the basis of a wide use of computers. As a result, the tactical capabilities of the hydroacoustic equipment changed qualitatively. The likelihood of detecting goals and classification of the received contact has increased. In addition, it became real at the same time to monitor several (up to six) targets and quickly detect changes in their maneuvering, automatically obtain information and continuously issue it into all conjugate systems and clearly, in a convenient application conveniently, to display on screens and screens, and If necessary, register.
Digital signal processing allowed the submarine passive location systems to determine only the noise of the bearer and the distance to it.
Finally, the integration of various systems based on computer simplified control over the work and maintenance of the GAS and allowed to reduce the service personnel, which is important for the relatively small water-disk of diesel submarines.
The main tract of the acoustic station is the noiselessness with a range of several tens of kilometers. In the low-frequency (220 Hz - 7 kHz) the signal reception range occurs on a conformal (combined with the body parts of the housing) a acoustic antenna consisting of piezoceramic hydrophones, and in high-frequency (8 kHz) - on a cylindrical antenna with hydrophones of lead zirconate, placed near Kiel . The cylindrical antenna also serves to track several (up to four) targets. Both noise redundancy channels complement each other. The surrounding space is overlooked by a rapid consistent survey of a large number of statically formed petals of the directional orientation. Detected noisy targets peeling with high accuracy equivalent method.
The active tract made it possible to conduct a circular review with the omnidirectional radiation of one parcel or when the series of parcels in sequentially changing directions, as well as emit single parcels in a specific direction. The accepted echo signals are displayed on the indicator screen and can be recorded to measure the Doppler frequency shift.
The path of passive location has three receiving antennas, installed flush with the housing in the nasal, middle and aft, for each side of the submarine. They take noise targets that are subject to correlation processing, which makes it possible to determine the place of target for three lines of position with sufficient accuracy. The path antennas can be used as an additional noise removal for the path.
The station provides directed and non-directional sound-powered communications.
The signal detection path of the hydrolyators allows you to detect pulse signals of various origins at a distance of several tens of kilometers, determine their frequency, duration and direction to the source of the signal.
In the construction of the station, integrated circuits are widely used, due to which its dimensions and weight are reduced, reliability is increased. Data on targets are displayed on two screens, automatically go to the AUM auto-packer of a torpedo shooting system where commands are produced for firing.
A simpler hydroacoustic station has been developed. It includes noiseing paths, echoes and passive location. Search and detection of goals is carried out in noiseing mode using the correction method of signal processing method. After the purpose is detected, the distance to it is measured by radiation of the directional single parcel or the method of passive location.
In order to increase the efficiency of using hydroacoustic observation tools on submarines, instruments also have devices for measuring the speed of sound propagation in water and for signaling about the beginning of the occurrence of cavitation of rowing screws, devices for controlling the level of own noise.
To increase the efficiency of the use of the GAS, there is a device for constructing radial paintings according to the input data on the actual distribution of the speed of propagation of sound with increasing depth. The system is capable of functioning in the simulator mode with the simulation of signals entering its entrance from various purposes. All current information entered into the system in the process of its combat work and produced by it can be recorded for subsequent playback and analysis. The system is served by one or two operators.
GAS of other types have cylindrical partitioned antennas. For a circular viewpace, 96 petals of the radiation pattern are statically formed.
The determination of the coordinates of the detected goals and tracking simultaneously is carried out in all modes using a computer. In active mode, to obtain a maximum range of action, it is provided for the coordination of radiation parameters (emitted power, frequency, type of modulation of the parcel) with actual hydrological conditions in the observation area.
In the detection mode of signals. Hydrolocators are determined by the bearing on the source of the signal, its frequency and amplitude, the duration of the pulses, the frequency of their following and classify the sources of radiation along the totality of all these features.
The station can also work in the auxiliary modes: simulator, insertion and automatic control of the technical condition that ensures detection of faulty modules.
All controls and two screens are located on the GAS console. On one of them with a tricolor indication, which represents a circular review indicator, simultaneously displayed in the central part. Full setting with its ship in the center and circular beads, and on the edges - complete text information On the accompanied goals (distances, delers, the values \u200b\u200bof Doppler shifts, courses, speeds), data on the course and the speed of your ship, about the mode and parameters of the operation of the GAS. Text hierarchical matrices are displayed on the second screen, the processing of which allows you to optimize the process of controlling the equipment. Such a presentation of information significantly simplifies the service and operation of the station and allows you to perform this to one operator.
In November 1983, Victor-III's APL received a task to remove the noise and other characteristics of the fourth American Ohio-type rocket.
According to the crew, the young ambitious captain of our submarine, inspired by examples of submariner heroes Patriotic War, I decided almost to go to the bay of the Sugostat base.
For acoustic disguise, the K-324 in Sargasso Sea came up under a small ship, which followed the appropriate course. Everything went fine, as suddenly the speed of our pl. Began to quickly fall, despite the increase in turbine turns to maximum.
No triggering and guesses of the crew to positive results led - the speed fell to three nodes.
We can do anything - I had to float. To pop up almost in mind the US banks, in the "Lair" itself, so to speak.
For the inspection of the main screw, the nasal tanks filled out, the boat acquired a decent differential on the nose and an emergency team, armed with two "kalashnikov" and two PM (all the Arsenal existing on the Soviet submarine) examined the feed part. So it is, some cable turned out to be wound on the shaft, very durable, not leaving, neither automatic queues: all efforts were vain.
The commander accepted the decision - to go to Cuba in an overnight position. It was then her and captured American pilots, sailors and tourists on pleasure yacht.
With a grief in half to Cuba, Delzli. The commander immediately called to the "carpet". But, contrary to the sad assumptions about his fate, the captain "At horse" returned, the captain wound on the screw by the desperate submariner was returned, turned out to be nothing more than the newest American hydroacoustic antenna that careless Americans were tested on an unpleasant ship.
Our scientists and technologists received invaluable materials to explore ...

Depending on the method of obtaining hydroacoustic information (according to the method of energy use), the hydroacoustic systems are divided into active hydroacoustic systems a) passive hydroacoustic systems active hydroacoustic system (means) - a device that forms and emits hydroacoustic signals in the aquatic environment and on the borders of its partition, accepts Reflected or emitted signals from underwater and surface objects. The equivalent terms of the active hydroacoustic system are active hydrolections, echo removal, echo location, or just hydrolection).
Active hydrolection is a method for detecting and determining the properties of underwater objects based on the radiation of hydroacoustic signals into an aqueous medium, as well as the reception and processing of echo signals, which arise as a result of reflection (or scattering) of acoustic waves from underwater objects. Hydroacoustic means (systems) providing active hydrolytics are called hydrocolocators, hydrogen stations (GLS), or hydrolerium paths (ch), echo removal paths (EP) and distance measurements (ID) for gas. Usually under the GLAS understand systems intended for detecting and measuring the distance to PL and other important underwater objects

Acoustic antenna (AA) is designed to convert electrical energy into acoustic and back. Input devices are used to pre-enhance the received signals, as well as for switching acoustic antenna with generator and receiving devices. The generator device generates radiation pulses with specified parameters. The receiving detection path channels solve problems of detecting underwater objects and a rough definition of their coordinates. Coordinate Channels are designed for accurate definition Coordinates of underwater objects, followed by issuing them to the weapon management system.
Systems of semi-automatic support of goals make it possible to carry out support for targets in semi-automatic mode with automatic removal of current coordinates. The listening channel makes it possible to listen to the received rumor signals for the classification of the hydroacoustic contact with the goal. The display system is an output device and is necessary for visual display of the information received and remove the target data. The management and synchronization system is a link between all the devices and the GLS systems.
The built-in training device (VUCU) is intended to work out operator skills by the target, as well as the skills on the management of GLS in various modes. The built-in automatic control system (ACC) allows you to monitor the main technical parameters of the GLS, to identify its faults. The GLS is included in the operation by supplying the supply voltages to all devices, for this, the station has a distribution shield on which the control system of the power supply system is displayed.

Conclusion of dissertation on the topic "Acoustics", Matvienko, Yuri Viktorovich
Main results:
1. The principles of constructing ultra-dotted systems were investigated and an analysis of the basic methods for determining the angular position of the source of tonal and broadband navigation signals during processing information of small-sized receiving antennas were studied.
Estimated expressions were obtained and the direction finding characteristics of amplitude delayrs with total and difference data processing were investigated.
The low potential accuracy of the simplest configuration systems containing one, two or three pairs of orthogonal receivers are noted with phase data processing methods and the need for complication of systems to increase accuracy is noted.
A method for the direction finding the source of tonal signals based on the use of antennas with a large number of receivers tightly placed on a circular base with the definition of the cumulative phase is also proposed, whose error can potentially be reduced to 0.1Gradus.
The calculated formulas and on the example of circular antennas with a large number of items are shown the connection of the course sensor data, roll and differential and their errors on the value of the measured navigation parameters and their errors.
Based on the maximum truthful method, the task of statistical processing of navigation data was solved when using discrete antennas of arbitrary configuration. In this case, the evaluation of the desired parameters is determined by joint processing of all pairs of channels taken with different scales. Weighting coefficients contain as a geometric component, equal to the derivative of the phase function according to the measured parameter and the energy equal to the signal-to-acting signal in the channel.
The estimated relationships are derived for the definition of bearing and the damping error for a number of the most common antenna configurations: linear, circular, combined.
A phase direction finder was developed based on the use of circular antennas of a large wave size with a limited number of elements.
The technology of reducing the number of processing channels with the preservation of the angular resolution is substantiated by separating the diapering procedure into two stages: coarse direction finding to determine the viewing sector and the exact solution of the bearing equation at a given initial approximation.
The possibility of permission of phase ambiguities arising during the operation of a sparse antennas by the methods of amplitude direction finding was justified.
Theoretically substantiated the achievement of the angular resolution of 0.1-0.2 degrees with the number of channels 6-8 and the wave size of the antenna 3-5 of the wavelengths of the navigation frequency.
Relations for calculating the bearing of a small-sized discrete antenna, the propagation time of the acoustic signal on the aperture of which is comparable to the average frequency of the received spectrum.
2. Research methods for assessing the accuracy of Hans UKB accuracy and developed methods for measuring their characteristics in laboratory and tool conditions.
To describe a discrete multi-element antenna, a vector function was proposed, each component of which describes the dedicated element of the antenna dependence of the phase of the acoustic signal from the direction of its arrival. The exact (experimental) definition of the function is mandatory when solving the task of delaying the navigation object.
A stand for certification of multi-element antennas, which is installed in a specialized hydroacoustic basin and includes a source of adjustable signals and a receiving system with a precision rotary platform and multichannel phase measurement equipment for radio pulse type signals.
An antenna certification technology has been developed, which consists in experimentally measuring the phase function of the antenna, the determination of analytical functions that approximate the obtained data and the use of them in solving the direction-finding equations, with the tabulation of the difference of the origin of the bearing and its true (installation) value in the form of an assessment of the systematic component of the error.
Multi-element receiving antennas for active samples of systems are developed and investigated, which provide the value of a systematic error around 0.5 Aradus.
A comparative analysis of the work of Hans dB and UBB in the conditions of a small sea with a fixed installation of the ACB receive antenna is carried out.
Analyzed the method for estimating relative angular measurements based on the processing of rangefinder data.
The method of certification of the UCB system in the small sea using the reference beacon based on the processing of rangefinder data is substantiated. It is shown that with the relative error of measuring the range, a few tenths percent, an error of the design value of the bearing for annea, which makes movement around UKB - antenna and a lighthouse on a closed trajectory, does not exceed one degree.
An analysis was carried out and the accuracy characteristics of the UCB system based on the results of work in the conditions of the deep sea were determined. As the reference data, the DB HANS data was used, the onboard navigation system and the depth sensor, rangefinder data. The feasibility of analyzing the differential variability of the rangefinder data to identify individual fragments of the ANPA movement trajectory and the possibility of reasonable averaging of angular data with the trajectory processing are shown. As a result of the analysis, the conclusion is justified about the error of angular measurements of about 0.5.
The technique of eliminating phase ambiguities arising from increasing the size of the measuring base is substantiated and experimentally tested by the statistical processing of multi-frequency signals.
The multi-element receiving antenna and the equipment of the radiation (reception) of complex signals were developed and experimentally studied, estimates of the system error were made, which constitute the tenths of hail.
3. The methods are investigated and means of a high-speed information transmission system for the hydroacoustic channel from the board of ancpa to the providing vessel.
Studies of construction of broadband piezo-converters were developed and specialized cylindrical and rod converters were developed with special orientation characteristics designed to work in communication system equipment: a highly efficient cylindrical converter was proposed with a bandwidth to three octave using thin matching layers of the horn configuration, which meets the requirements for work in a small sea; A variety of resonant converter is proposed for radiation and reception of multi-frequency signals, made in the form of a set of coaxial piezocylinders; Piston piezopraverters are proposed with a single-sided type HN to work in a vertical signal propagation channel.
Analyzed the structure of the data transmission system for the multipath channel of communication with the adaptation of the processing circuit through the data block of the final length. The transmission of the information block is preceded by the procedure for setting the receiver settings, the temporary block size is determined current status Communication channel. The methods of numerical modeling analyzed the features of selection of connected signals and shows the expediency of using the signal to combined phase and frequency manipulation.
A methodology for estimating the pulse characteristics of the communication channel and refinement of the moment of synchronization by transmitting and processing a series of pulses of the alternating phase is proposed.
A diagram of receiving signaling system signals of a multi-element navigation antenna with the realization of the spatial filtering of the direct beam under the conditions of multipath distribution based on data on the angular position of the source of signals and interference received during the operation of Hans UKB is proposed.
Studies have been made and justified the possibility of transmitting information in a multi-frequency communication channel with a preliminary alignment of the through amplitude frequency response of the channel and selecting the current message based on a comparative analysis of energy in each frequency channel. Experimental studies of such a processing system in a very small sea confirmed the possibility of using equipment for transmitting graphic images at a speed of about 3000bit / s at a low probability of errors.
4. For onboard navigation, the underwater robot is designed and integrated into the complex Doppler Lag.
Studies completed and developed specialized lag antennas with high echo sensitivity obtained due to the optimal acoustonic mechanical coordination of the antenna's piezo-methods with a working environment.
To increase the speed of lag, a method of spectral processing of short pulse signals is proposed and implemented, providing high frequency resolution due to the formation of long quasi-coherent implementations of reflected signals. The method allows you to determine the speed components with the minimum dispersion in one second.
Designed and used as part of the ANPA Experimental Sample Doppler Lag
A technique of graduation of lag in full-scale conditions was developed by calculating the ANPA velocity on the range finding data of Hans.
5. Designed, tested and tested in real operations a hydroacoustic navigation complex, which ensures the formation of a navigation information picture of the movement of the mission aboard the providing vessel and anca, consisting of hydroacoustic navigation tools, transmission of information and measurement of absolute speed.
Designed, tested in a small and deep sea and integrated into the Navigation Complex of the Hans UKB, which includes: a synchronized source of the navigation signal at the facility, a ship processing complex with a receiving antenna on a cable cable, GPS receiver. The system has the following characteristics: range - 6-10 km; The error of measurement of the bearing is less than 1 degrees; The limit measurement error is 0.5%. Experimentally confirmed the possibility of operating the system in the position of the position of the anca, which makes a long transition along the extended object with the movement of the providing vessel and towing the receiving antenna at a speed of up to 5 nodes.
Designed, tested and used as part of a hidden apparatus a high-frequency system of navigation ukb with the placement of the source on board the vessel, and the receiver on the machine.
Designed and tested in the composition of the hydroacoustic means of navigation and information support, an APA equipment transmission equipment for operational control of the state of surveillance and search work in the conditions of the deep sea and the vertical communication channel. The equipment provides data transmission at a speed of 4000bit / s, with a probability of errors about one percent, which ensures the transmission of the image frames for 45c.
Designed, tested and integrated into the onboard navigation system Doppler Lag, providing the measurement of the absolute velocity of the anca in the range of speeds 0-2m / s with an error of 1-2 cm / s.
The technology of application of the navigation complex is proposed:
Hans DB - for multiple Runs of the anca in the dedicated areas with searching in areas with increased requirements for accuracy.
Hans UKB if there is no longer transitions when tracking extended objects or moving purposes, in case of emergency starts of the anca, in the case of secretive launches.<
To with the calculation of the trajectories on the number - when the anca is released at a specified point, when adding to the use of TV systems.
The successful work of the complex in the composition of the anc does not demonstrate when performing real search engines in the ocean.

Russian underwater hydroacience at the turn of the XXI century
Military hydroacience - elite science, the development of which can afford only a strong state
Herman Alexandrov
Having the highest scientific and technical potential (the company employs 13 doctors and more than 60 candidates of science), the concern develops the following priority directions of domestic hydroacoustics:
Multifunctional passive and active hydroacoustic complexes (gas) and systems (GAS) lighting underwater furnishings in the ocean, including submarines, surface ships, aircraft, underwater swimmers detection systems;
Systems with flexible extended towed antennas for working in a wide frequency range for surface ships and submarines, as well as stationary;
Active, passive and active passive stationary hydroacoustic complexes for protecting the shelf area from unauthorized penetration of surface ships and submarines;
Hydroacoustic navigation and search and survey systems ";
Hydroacoustic transducers, antennas, phased antenna arrays of complex shape having up to several thousand receiving channels;
Acoustic screens and sound transparent fairings;
Information transmission systems for the hydroacoustic channel;
adaptive systems for processing hydroacoustic information in conditions of complex hydro-coastal and signal interference;
Classifiers of goals for their signatures and by the fine structure of the sound field;
Sound speed meters for surface ships and submarines.
Concern Today is ten enterprises located in St. Petersburg and the Leningrad Region, Taganrog, Volgograd, Severodvinsk, Republic of Karelia, and research institutes, factories on the serial production of hydroacoustic equipment, specialized equipment for the maintenance of equipment at facilities, polygons. These are five thousand high-class specialists - engineers, workers, scientists, more than 25% of whom are young people.
The staff of the enterprise developed almost all serially produced GAK pl ("Rubin", "Ocean", "Rubikon", "Skat", Skat-Datrhm, Skat-3), a number of hydroacoustic complexes and systems for surface ships ("Platinum ", Polynoma, the station of detection of underwater swimmers" Pallada "), stationary systems" Liman "," Volkhov "," Agam "," Dniester ".
Hydroacoustic systems for submarines created by the enterprise are unique technical means, the creation of which requires the highest knowledge and tremendous experience in hydroacoustics. As one too, the task of detecting a submarine with a noise reducer is similar to the task of detecting the flame of the candle at a distance of several kilometers in a bright sunny day, and yet for a submarine located in the underwater position of the GAK - almost the only source of information about the environment . The main tasks solved by the submarine hydroacoustic complex - the detection of submarines, surface ships, torpedo in noiseless mode, automatic support of goals, definition of their coordinates, classification of goals, detection and delaying targets in hydrogen mode, intercepting hydroacoustic signals in a wide frequency range, sound-powered Communication at large distances, provision of a review of the near environment and sailing safety, lighting ice environment when swimming under ice, providing minno-torpedo protection of the ship, solving the navigation tasks - measurement of the speed, depth, place, etc. In addition to these tasks, the complex must have a powerful system of automated control, a self-observation system, must continuously produce the most complex hydrological calculations to ensure the functioning of all systems and to predict the situation in the area of \u200b\u200bthe submarine. The complex has simulators of all systems of the hydroacoustic complex, ensuring training and training of personnel.
The basis of any hydroacoustic complex - antennas, phased discrete grilles of complex shapes consisting of piezoceramic converters, which should ensure the reception of signals from the water medium on a boat experiencing huge loads due to hydrostatic pressure. The task of the gas is to detect these signals against the background of own noise, noise of streamlining when the boat, marine noise that interfere with the goals, and still masses of factors masking a useful signal.
Modern gas is the most complex digital complex that processes great information streams in real time (each complex of the complex consists of thousands of thousands, and then tens of thousands of individual elements, each of which must be processed synchronously with all other). Its work is possible only when using the latest multiprocessor systems that ensure the problem of simultaneous, in space, and multidia-band, frequency, observation of the surrounding acoustic fields.
The most important and most responsible element of the complex is the display devices received information. When creating these devices, not only scientific and technical, but also ergonomic, psychological problems are solved - it is not enough to take a signal from the external environment, it is necessary that the operators of the complex (and this is the minimum number of people) at each moment of time had a complete picture of the surrounding environment, controlling and actually Safety of the ship, and the movement of many goals, surface, underwater, air, representing a potential threat or interest to the submarine. And the developers are constantly balanced on the verge of problem - on the one hand, to display the maximum amount of information processed by the complex, and the necessary operator, on the other hand, not to disturb the "Miller rule", which limits the amount of information capable of being learned at the same time.
An important feature of the hydroacoustic systems, especially the antennas, is the requirements for their strength, durability, the ability to work without repair and replacement for a very long time - in the conditions of combat service, repair the hydroacoustic antenna is usually impossible.
Modern gas cannot be considered as a self-sufficient, closed system, and only as an element of an integrated Surveillance System of the PL, receiving and using continuously updated a priori information on the purposes of non-acoustic detection systems, exploration, etc., and issuing information about the changing underwater environment in the system. Analyzing tactical situations and outstanding recommendations on the use of various gas regimes in this situation.
The development of hydroacoustic complexes for a submarine is a continuous competition with the developers of a potential enemy, on the one hand, since the most important task of the GAC is to provide at least parity in the duel situation (the enemy hears and recognizes you, and you are at the same distance), and you need all the forces and tools to increase the range of gas, and mainly in passive mode of noiselessness, which allows to detect the goals, not demoing its own location, and with shipbuilders, projectors of underwater ships, on the other, since the noise of submarines decreases with each new generation, with each new project Even with each new built ship, and you need to detect a signal, in terms of the level of smaller in order than the surrounding sea noises. And it is obvious that the creation of a modern hydroacoustic complex for submarines of the XXI century is the joint work of the developers of the complex and the developers of the boat, the common efforts of the design and placing elements of the gas-made on the ship in such a way that its work in these conditions is most effective.
The design of the design of GAK PL, existing in our institute, allows you to highlight the main problem areas, from which it is worth expecting a significant increase in efficiency in the near future.
1. Guck with conformal and conformal-cover antenna
Reducing the noise of the PL associated with the efforts of the projectors for optimizing the technical solutions of the structures of its hull and mechanisms led to a noticeable reduction in the range of the gas in modern PL. An increase in the aperture of traditional antennas (spherical or cylindrical) is limited to the geometry of the nasal tip of the case. An obvious re-suction in this situation was the creation of antenna conformal (combined with the intensities of PL) antennas, the total area, and therefore the energy potential of which is significantly superior to similar indicators for trap-diving antennas. The first experience in creating such antennas was quite successful.
An even more promising direction seems to create conform and coating antennas located along the board of PL. The length of such antennas can be tens of meters, and the area is more than a hundred square meters. The creation of such systems is associated with the need to permit a number of technical problems.
The conformal-coating antenna is located in the region of the prevailing effect of inhomogeneous waves caused by structural interference, as well as a hindrance of hydrodynamic origin, including the incident flow arising from the excitation. Acoustic screens, traditionally used to reduce the effects of interference to the antenna, are not effective enough in the low-frequency range of the onboard antennas. Possible ways to ensure the effective work of onboard antennas, judging by foreign experience, are, firstly, the constructive placement of the most noisy machines and mechanisms plus in such a way that their effect on the onboard systems is minimal, and secondly, the use of algorithmic methods for reducing the impact of structural Interference on the HAC tract (adaptive methods for compensation for structural interference, including using vibrator placed in the immediate vicinity of the antenna). The use of so-called "vector-phase" methods for processing information, which can be used to increase the efficiency of the complex, due to the joint processing of pressure fields and oscillatory speeds. Another way to reduce the effect of hydrodynamic interference influencing the effectiveness of conformal-cover antennas, is the use of film converters (plates from PVDF), allowing the averaging on an area of \u200b\u200b1.0x0.5 m significantly (judging by the data in the literature - up to 20 dB) reduce Effect of hydrodynamic interference on a gas tract.
2. Adaptive hydroacoustic information processing algorithms agreed with the distribution medium
By "adaptation" traditionally understand the ability of the system to change its parameters, depending on the change in environmental conditions in order to maintain its effectiveness. In relation to the processing algorithms under the term "adaptation", the coordination of the processing path with the characteristics of signals and interference is implied. Adaptive algorithms are widely used in modern complexes, and their effectiveness is determined mainly by the hardware resources of the complex. More modern are algorithms that take into account the space-time variability of the signal propagation channel. The use of such algorithms allows you to simultaneously solve the tasks of detection, target designation and classification using a priori information about the signal propagation channel. The source of such information can be adaptive dynamic oceanological models, predicting with sufficient accuracy of temperature distribution, density, salinity and some other parameters of the medium in the area of \u200b\u200baction of the PL. Such models exist and are widely used abroad. The use of sufficiently reliable estimates of the parameters of the distribution channel allows, judging by theoretical estimates, it is several times to improve the accuracy of determining the coordinates of the target.
3. Acoustic systems placed on controlled unmanned underwater devices, decisive tasks of polystatic detection in active mode, as well as the task of searching for the heated bottom objects
The submarine itself is a huge structure, more than a hundred meters long, and not all tasks, the solution of which is necessary to ensure their own security, can be solved by placing the hydroacoustic systems on the ship itself. One of these tasks is the detection of bottom and soluble objects representing the danger to the ship. To consider the object, you need to get closer to it as a close distance, without creating threats to your own safety. One possible ways to solve this problem is the creation of a managed underwater unmanned apparatus placed on a submarine capable of independently or by controlling a wired or sound-powered connection to approach the object of interest and classify it, and if necessary to destroy. In fact, the task is similar to the creation of the hydroacoustic complex itself, but a miniature, having a battery propeller placed on a small self-propelled device, capable of refurbing from the submarine in a submerged state, and then stick back, while providing a constant double-sided bond. In the US, such devices are created and included in the armament of submarines of the last generation (type "Virginia").
4. Development and creation of new materials for hydroacoustic transducers that differ less than weighing and cost
Piezoceramic converters, from which antennas for submarines are created - extremely complex structures, piezoceramics in itself - a very fragile material, and considerable efforts are required to give it strength, while maintaining efficiency. And a long time is a search for a material that has the same properties of transformation of oscillation energy into electrical, but representing a polymer, durable, light, technological.
Technological efforts abroad led to the creation of polymer films of the PVDF type, which have a piezoene effect and convenient for use in the designs of cover antennas (placed on board a boat). The problem here is primarily in the technology of creating thick films that ensure sufficient antenna efficiency. Even more promising, it seems the idea of \u200b\u200bcreating a material with the properties of piezoceramics, on the one hand, and the properties of the protective screen, drowning (or scattering) signals of the enemy hydrolector, and reduces the eigencraft ship's noise. Such material (piezoresine), applied to the submarine body, actually makes a hydroacoustic antenna entire body of the ship, providing a significant increase in the efficiency of hydroacoustic agents. Analysis of foreign publications shows that in the United States such developments have passed into the stage of prototypes, while in recent decades there is no progress in this on the rule.
5. Classification of targets
The task of classification in hydroacoustics is the most difficult problem associated with the need to determine the class of the target according to information obtained in noiseing mode (to a lesser extent - according to the active mode). At first glance, the problem is solved easily - just register the spectrum of the noise object, compared with the database, and get the answer - what is the object, with accuracy up to the commander's last name. In fact, the spectrum of the goal depends on the speed of the course, the purpose of the target, observed by the hydroacoustic complex, the spectrum contains distortions due to the passage of the signal through a randomly inhomogeneous channel of distribution (aqueous medium), and therefore depends on distance, weather, the area of \u200b\u200baction and many other reasons making the task of recognition on the spectrum practically intractable. Therefore, other approaches are used in the domestic classification related to the analysis of characteristic features inherent in a specific class of goals. Another problem that requires serious scientific research, but the necessary necessary - the classification of bottom and coiled objects associated with the recognition of mines. It is known and confirmed experimentally that the dolphins certainly confidently recognize the air and water-compared objects made of metal, plastic, wood. The task of researchers is to develop methods and algorithms that implement the same procedure that performs a dolphin that solves a similar task.
6. The task of self-defense
Self-defense is a comprehensive task of ensuring the safety of the ship (including anti-nuclear protection), which includes detection, classification, target designation, issuing source data on the use of weapons and (or) technical means of opposition. The peculiarity of this problem is a comprehensive use of data from various subsystems for gas, identification of data from various sources, and providing information interaction with other vehicle systems providing weapons.
The above is only a small part of those promising areas of research that need to be engaged in to increase the efficiency of the hydroacoustic weapons created. But from the idea to the product - a long way, requiring advanced technologies, a modern research and experimental base, a developed infrastructure for the production of necessary materials for hydroacoustic transducers and antennas, etc. It should be noted that recent years are characterized by our company a serious technical re-equipment of the production and testing base, which has become possible thanks to funding under a variety of federal targeted programs, both civil and special appointments, which leads to the Ministry of Industry and Trade of the Russian Federation. Thanks to this financial support over the past five years, it was possible to completely repaired and significantly upgrade the largest hydroacoustic test pool in Europe, located on the territory of the Okeanpribor Concern OJSC, to radically update the production facilities of the concern of serial plants, so that the Taganrog plant "Surbo" became The most perfect instrument-making enterprise in the south of Russia. We create new production - piezaterials, printed circuit boards, in the future - the construction of new industrial and scientific spaces, stands for setting up and passing equipment. After 2-3 years, the production and scientific power of the enterprise, supported by the "Bank of Data" of new ideas and developments, will begin to create a hydroacoustic armament of the fifth generation, so the navy-sea fleet.
