A known computer system for processing data (see USSR author's certificate NS 424148, IPC G06F 15/16, publ. 17941), containing central processors, memory blocks, peripheral processors forming a group of devices with high overall performance and external unified information exchange devices with external executive equipment. The disadvantage of this system is the lack of the ability to exchange information between all processors, which reduces the effective performance of the system, in addition, it is impossible to simultaneously exchange with external subscribers.

A microprocessor system is also known (see US patent. No. 3959775, IPPC G06F 15/16, publ. 19762), consisting of several microprocessors connected via a system bus with shared memory, through which information is exchanged between all processors. Exchange control is carried out by the system bus distributor. The disadvantage of this system is the low bandwidth of the exchange of information through shared memory, as well as the lack of control over the state of each microprocessor, which limits the functionality and reliability of the considered system.

Also known is a multiprocessor ship data processing system (see the certificate of the Russian Federation for utility model N ° 4395 MPK7 G06F 15/16, publ. 1997), containing microprocessors, information exchange devices, units

I / O, external storage devices, the first and second interface exchange lines, the inter-highway exchange adapter, a control panel, data input units from ship information sources, while microprocessors are connected to the first line through information exchange devices, whose second inputs and outputs are through input units - outputs form w groups of system outputs to w actuators, two external storage devices are connected to the second line through the interface unit, through the corresponding adapters for display, control panel, as well as a timer - the system controller through the third input-output of the inter-bus communication adapter, to the first input-output of which the trunk is connected, and the data input adapter to the second input.

Such a system has insufficient reliability in the event of failure of individual elements of the system (for example, an inter-trunk adapter).

The computer system of the ship’s electronic countermeasures complex is known (see the certificate of the Russian Federation for utility model XQ 19428, MPK7 G06F 15/16, publ. 2001), containing six computers, five graphic information display devices, eight long-term storage devices, six random-access memory devices , LAN adapters, system interface lines, analog and digital input-output blocks and a pointing device. This system does not have a sufficient information exchange rate, which limits the possibilities for analyzing the radio-electronic situation and tracking radiating targets.

Closest to the claimed technical solution for the problem and the instrumentation is an automated air defense control system (see certificates of the Russian Federation. No. 16035, IPC7 G06F 15/16, publ. 2000), containing a local area network (LAN) Computers, one of which is central (CEC), data transmission equipment, topographic location, navigation, a printing device and operator workstations containing a computer, display, keyboard and mouse-type manipulator, characterized in that the system also contains I am guiding a computer LAN, a hard disk drive, a plotter and a large display screen, the first LAN designed for exchanging real-time information, bitwise connects the first group of PC terminals with the corresponding computer outputs for workstations, and the second LAN for exchanging tactical information, bitwise connects the second group of terminals of the computer with the corresponding terminals of the printing device, hard disk drive, plotter and large display screen, the third group of PCB outputs is connected via an internal exchange line with the corresponding terminals of data transmission, topographic and navigation equipment, the PC contains three processors, the first of which is connected to the first group of PCM outputs, the second to the second group of PCM terminals, and the third to the third the group of conclusions of the computers that form the internal backbone of the exchange, the first and second LANs have conclusions for communication with computers of other automated control systems, external communications of data transmission equipment are information channels of the system. This system uses radial construction of an information exchange network, which allows to reduce the intensity of information exchange in each specific exchange line. The disadvantage of this system is the lack of hardware that provides automatic processing of information about the radio environment.

The objective of the utility model is to create an automated control system for a complex of electronic countermeasures, capable of automatically processing information about radiating targets, identifying them with determining the type and operating modes, tracking radiating targets and controlling jamming means.

The work of the automated control system of a complex of electronic countermeasures (REP) is as follows.

It is designed to solve the following problems:

-analysis of the electronic environment (REO) with the provision of automatic processing of information about emitting targets with the determination of their type and operating modes and tracking of up to 100 emitting enemy RES;

- display of electronic environment and determination of the type of tactical situation,

- the formation of signs such as a tactical situation and the development of strategies and tactics for using REP tools;

-automatic development of target designation by means of REP of the ship and control over their execution;

-exchange of necessary information with general ship systems in accordance with the protocols of ideological, informational and technical conjugation;

-documentation of information about detected radiation sources and executable plans for using REP facilities;

-controlling the process of control (diagnostics) of the complex and displaying the results of control;

- management of processes for ensuring electromagnetic compatibility with the display of the necessary information.

When the system power is turned on, all devices are automatically switched on to the test self-control mode, at the end of which the system is ready for operation.

For each signal received by the direction finder, a pulse parameter code form is received in the electronic module 2i or 22. The electronic module 1 or li provides the formation of a panorama of all processed RTO signals, in parallel with this, the detection of radiation sources, the determination of their additional radio technology iWiH

parameters and tracking parameters along the bearing, as well as the formation of a non-passing panorama of all received signals. The inclusion of electronic modules 2 or 22 between the receiver of the complex and the multiprocessor computer made it possible to reduce the bandwidth requirements of the transmission channel between them, since the information about the emitting targets entering the computer is no longer a stream of monopulse parameters based on a maximum flow of 400,000 pulses per second, and regular informational reports on the results of the initial processing of the aforementioned stream. In addition, it became possible to combine the control channel and the channel for transmitting data on the PTO into a single serial channel using standardized circuitry solutions. The structure of electronic modules 2 or 22 allows them to be executed on commercially manufactured elements. The exchange microcontroller is a 16-bit Fujitsu microcontroller. As signal processors, modern high-speed 16-bit digital signal processors from Analog Devices with a large amount of memory on a chip are used. The basis of the interface and synchronization circuitry is Altera's highly integrated programmable logic integrated circuits (FPGAs) of high degree of integration EPF10K30.

Automated workstation 10, designed to control the operation of the complex in all modes and display information, and includes a computer 12 - a computer Lippert S-AT96-FOX2-VE200, which is the control computer of the complex that solves the following tasks:

-identification, ranking and classification of goals;

-development of a target distribution plan (CD);

-development of corrections of the plan of the CR;

heading of the ship and pitching angles for indirect stabilization of the electrical axis of the antennas of the equipment of active interference in space in the conditions of quality and pointing it at the object of counteraction;

preparing information for documentation.

All information is displayed on the display 13, made in the form of a graphic liquid crystal panel.

The device 15 is designed to control the guidance of the antennas of the active interference equipment of the port and starboard. Guidance is carried out on the course angle and elevation. Information about the position of the antennas is taken in the form of voltages from the sensors located in the antenna posts.

Workplace 9 is designed to control a complex of shot interference. Computer 12 - Lippert S-AT96-FOX2-VE200 computer, designed to control the operation of the interface, as well as to generate information display signals on the Planar EL640.480-AA1 electroluminescent indicator and generate electrical signals for interfacing with the shot interference complex.

In the inventive automated system of the electronic countermeasures complex, a modular construction principle is used that allows you to modify devices during operation by redistributing, building up, modifying tasks assigned to the components of the system, without resorting to modifications to the hardware, using radial construction of an information exchange network, which allows increase the reliability of information exchange, reduce the intensity of information exchange in each specific line of exchange, while it remains possible to add information nodes to each branch of the network.

The algorithm for processing single-pulse codes in electronic modules 2 or 22 is based on a variation of the method of fixing a compact group of signal descriptions in the input space using a strobe and plotting histograms of signal parameter values from the quantization discs of the bearing and the carrier frequency. In this case, the value of the binary parameter code in the signal descriptions (bearing and carrier frequency) is used as the address of the histogram element. The use of the histogram method allows to achieve advantages, since:

- there is no need to search for a gate with which the signal description is identified;

- there is no need to organize interaction between gates during parallel processing, when the signal description can correspond to several gates;

- since the histogram is an organized structure, it is easier to process it further in a digital processor in order to eliminate fragmentation of the radiation parameters of radio electronic means (RES).

In addition to the indicated processing scheme, the statistical processing algorithm is also implemented in electronic modules 2 or 22 to display on the screen an automated workstation 10 of all received RTO signals, in addition to displaying the general radio engineering situation for all purposes accompanied by RTO equipment.
