Hydroacoustic complexes (SAC) are the basis of the information system of submarines (submarines). According to the authoritative periodical Jaiies 7, all modern submarines are equipped only with a hull. A typical complete set of HAK PL consists of the following tracts, which are sometimes called sonar stations

After pre-processing, the signals are sent for further processing to the central computing system (CVS), where the information flows from various paths are integrated. The prepared information enters the display, registration, documentation and control system (SORDiU) and is presented to the operator in alphanumeric or graphic format, stored on peripheral devices, and transmitted to systems external to the HAC.

The control signals are transmitted via a common bus, information is exchanged between SORDiU, TsVS, various channels preliminary processing equipment, and generator devices.

In the prototype device there are also classification systems, an automated system for monitoring and troubleshooting, which are generated by software, as well as a path for monitoring interference and noise, and a secondary power supply system.

The noise-detecting path (SHP) of the proposed HAC consists of the main nose receiving antenna 1 and the first pre-treatment equipment (APO) 2 connected in series with the main nose receiving antenna 1. APO 2 is placed in a sealed capsule inside the main nose receiving antenna 1 (antenna connection 1 with apparatus 2 shown in figure 1 by a dashed arrow). Devices 1, 2 are multi-channel, consist of N X M channels, where N is the number of XI (spatial channels) in the horizontal plane, M is the number of XN (spatial channels) in the vertical plane. Through a common bus 3 HAC tract ShP connected to the DAC 4 and SORDiU 5.

The GL path includes a chopping emitting antenna 6, and identical on-board emitting antennas 7, 8, as well as a first generator device (GU) 9 connected in series with antennas 6,7,8. Antenna 6 is located in the cabin of the cabin 10, antennas 7, 8 - on both sides of the submarine. The listed equipment of the GL path works in the radiation mode, receiving commands and parameters of the radiation mode from DSP 4 and SORDiU 5. Receiving echo signals from the target in the GL path is carried out by antenna 1 and APO 2 in the same way as in the ШП path.

Work in the frequency range of the FS path for the OGS path is provided by the main nasal receiving antenna 1 and, accordingly, APO 2. The detection of signals whose range lies above the frequency range of the main nasal antenna 1 is performed with

using the first pharmacy 11 and the second antenna 12 located in the fencing

10, as well as the third antenna of the OGS tract 13, the blocks of which 13.1, 13.2, 13.3 and 13.4 are located in the nose fairing 14. along the sides and in the fencing 10 (see Fig. 1). With antennas

11,12 and the blocks of the antenna 13 are connected to the second APO 15.

The bow and stern radiating antennas 16 and 17 of the communication and recognition path are connected in series with the third GU 18, which is controlled via bus 3 from the DAC 4 and SORDiU 5. The reception of communication signals is carried out to the main nose receiving antenna 1 and then similar to the steampunk path. The analysis of communication signals is carried out in DAC 4.

In the mine detection path (MI) there is a receiving-emitting antenna 19 and connected to it through a receive / transmit switch (not shown in FIG. 1), a third GU 20 and a third APO 21. Devices 20, 21, as in other paths, through the bus 3 is connected to the DAC 4 and SORDiU 5. The rotation of the antenna ХН in the vertical plane, depending on the possibilities of placing the hardware on the submarine, can be performed by mechanical rotation of the antenna or by electronic scanning 12, 13.

In the noise-detecting path with a flexible long towed antenna (NF IF path), the antenna 22 is connected to the fourth APO 24 via a cable 23 and a current collector (not shown in FIG. 1). Next, the signal from the NF IF path through the bus 3 is sent to the DAC and in SORDiU. The GPBA setting-sampling device, which is not shown in FIG. 1, is controlled by commands from SORDiU. The location of this device and its design is determined by the design features of the submarine and is considered in Ref. 18.

Receiving antennas 1, 11-13, 22 are designed to convert the energy of mechanical (acoustic) vibrations into electrical energy; radiating antennas 6-8, 16.17 - electrical energy into mechanical energy; antenna 19 is reversible. Antennas of the claimed utility model do not have specificity; methods for calculating the characteristics of such antennas and designs are known 12. The formation of directivity characteristics is also reflected in literature 12, pp. 56-79, 13, p. 32-50.

In the generating devices 9, 18, 20, a pulse signal of the required power is generated; control signals of signal parameters are generated in SORDiU 5 and TsVS 4. Block diagrams of generating devices, their structure and methods of formation are described, in particular, in 14, pp. 91-95, 15.

Pre-processing equipment 2, 15, 21, 24 is performed on analog or analog-digital means. Typical functions of this equipment are: amplification, filtering, time-frequency processing, data conversion from analog to digital. These issues are covered in books 14, pp. 99-106, 16, pp. 295-298.

The central computing system 4 and the display, registration, documentation and control system 5 are systems that implement their functions in all paths and systems of the HAC. DAC and SORDiU work with data in digital form. The basis of the work of these systems is information processing algorithms implemented by software. Processing algorithms, depending on the configuration of the HAC, can be redistributed between the pre-processing equipment (in reception) or generator devices (in radiation) and the DAC. Thus, the formation of directivity characteristics can be carried out in pre-processing equipment in one HAC configuration, and in the other, by digital methods in a DAC. Similarly for generator devices: a pulse signal with the necessary parameters can be completely formed in a DAC, and in a generator device it will only be amplified in power; in another implementation, only the command word containing the necessary parameters of the signal to be emitted comes from the DAC (or SORDiU) to the generator device.

SORDiU consists of two remotes, in each of which there are two displays, controls (keyboard, buttons, sockets). The structure of the console is similar to the structure of a personal computer. Software forms a multi-window alphanumeric and graphic display of information. Typical peripheral devices are connected to the various ports of the console: telephone, speakerphone, printer, recorder, recorder on a magneto-optical disk, etc. 14, p. 108-112, 17, p. 41821.

In FIG. 1, the interference monitoring and measurement path is not shown, the sensors of which are distributed over acoustic antennas, and the equipment is combined with the equipment of the corresponding paths. Not shown in FIG. 1 power supply system (its construction and features are described in works 15, 17) is designed to convert the voltage of a standard ship network to the necessary currents and voltages of the HAC radio-electronic equipment.

The classification system, the automated control and troubleshooting system are based entirely on software-oriented tools, the algorithms are described in books 16, pp. 353-388, 17, pp. 492-509.

The following main functions are implemented by software in the declared submarine hull:

secondary processing of information revealing the fine structure of the signal;

- making a decision about finding a target; automatic target tracking;

-identification of classification and identification features of the goal;

-analysis of the jamming situation;

- predicted estimates of the detection distances of targets, light zones, taking into account the current noise signal situation;

-preparation of data arrays for display, registration, documentation, transfer to external systems;

-formation of display patterns;

-monitoring the state of operating modes, including individual units of equipment;

-management of the operating modes of the HAC and the parameters of the modes;

-realization of connections with external devices.

The work of the proposed submarine hull is as follows ..

The operation of the SAC is controlled by the operators, which are located behind the SORDiU 5 consoles. The main operation mode of the SAC of the submarine is receiving, while the working paths are the power supply, power supply, low frequency, OGS, and communication channels. The GL and MI paths, as well as the active operation of the communication path, are switched on to radiation by commands from SORDiU. The receiving paths operate simultaneously and independently of each other. The received signals through the acoustic antennas 1,1113,22 arrive in the first and fourth APOs 2, 15, 21, 24, are filtered out according to the frequency ranges, their time-frequency processing is carried out 17, 18. Next, the received signals are transmitted to DIC 4, where program means, based on the algorithms adopted by the SAC, secondary signal processing is performed as described above for software. The signals from the targets are processed using classification algorithms, the elements of movement and the coordinates of the targets are determined, the data received from the same target by different paths is generalized; Depending on the selected display and registration menu, the processed data forms a graphic and alphanumeric image on the SORDiU 5 screens, the data is transmitted to peripheral devices. The operator decides on the allocation of targets for automatic tracking and transmits the appropriate command. The data about the goals after they are summarized are collected in a form that is transferred to devices external to the HAC (in Fig. 1 this relationship is not shown). Signals identified as communication signals

(or identification), are decrypted and transmitted to external devices (to the signalman, to the encryption post of the submarine - in the form of alphanumeric characters, speech characters).

At the command of the operator from SORDiU, the active HAC modes are activated - radiation in the sonar, communication and recognition, mine detection paths. The radiation command comes in DAC 4 and is processed. The configuration of the active path may be such that a complex command is generated in the digital computer that contains the codes of the parameters of the radiation mode, via bus 3 this command is transmitted to the first (second, third) GU 9 (18, 20), where a powerful analog signal of the radiation supplied in antennas 6-8 (16, 17, 19). With a different configuration, DACs 4 form arrays of radiation signals, are transmitted via bus 3 to the GU, where they are converted to analog form, amplified by power and transmitted further to the antennas. The reception of the echo signals of the GL path and communication signals is carried out by the equipment of the power supply path (antenna 1, the first APO 2) in the same way as in the power supply path itself. In the MI path, the echo signal is received by the antenna 19, which is connected to the APO 21 using the receive / transmit switch. Next, all received signals are sent via bus 3 to the DIC 4, they are processed similar to the processing of the received path signals, but taking into account the specifics of the active modes signals 14, p. 119-141, 17, p. 397-401. The data of the echo signals of the GL and MI modes are presented to the HAC operator in alphanumeric or graphic form similar to the signals of the receiving paths.

Control modes (troubleshooting, noise control) are activated by the operator using the remote control, while automatically during the operation of the HAC continuous monitoring of the operation of all devices included in the HAC is performed, information appears on the SORDIU screen or as an audio signal only if a malfunction is detected.

The inventive utility model of the sonar complex of a submarine can be used as the basis of an information monitoring system for modern diesel and nuclear submarines, as well as for research complexes, tourist and transport submarines 19.
