Description

The invention relates to the field of simulators and is intended for the training and training of navigators-operators of anti-submarine defense (PLO) systems equipped with a radio hydroacoustic (containing radar (radar) and hydroacoustic (GAS) station) sighting and search system (PPS), search, detection and defeat of surface and underwater targets, both with the help of equipment of one PPS carrier, and a group of interacting carriers.

The aim of the present invention is to expand the functionality of the simulator to provide imitation of the work of the radio-acoustic complex of the faculty of the group of interacting LA PLO.

To achieve this goal, a prototype device containing sequentially connected target parameter setter, coordinate transformer, radar situation shaper, radar equipment simulator, airborne homing device and control and monitoring device, submarine current coordinates calculator, sonar shaper, sonar simulator , a calculator of the trajectories of interacting aircraft, an adder of coordinates, a calculator of coordinates of the submarines relative to the interacting aircraft, a simulator of an exchange system formation (SDI).

In this case, the calculator of the current coordinates of the submarine, the calculator of the trajectories of the interacting aircraft, and the shaper of hydroacoustic signals are connected to the target parameter setter. The second input of the sonar shaper is connected to the calculator of the current coordinates of the submarine, and the output to the simulator of the GAS equipment. The inputs of the coordinate adder are connected to the calculator of the current coordinates of the submarine and the calculator of the trajectories of the interacting aircraft, and the output to the calculator of coordinates of the submarine relative to the interacting aircraft. The second outputs of the calculator of the current coordinates of the submarine and the calculator of the trajectories of the interacting aircraft are connected to the coordinate transformer. The inputs of the SDI simulator are connected to the simulator of the GAS equipment and the coordinate calculator of the submarines relative to the interacting aircraft.

In addition, the simulator of the SDI and the simulator of the GAS equipment are connected to the PMP and the control and monitoring device.

The drawing of figure 1 shows the structural diagram of the proposed simulator navigator radio-acoustic complex.

The proposed simulator consists of a target parameter setter 1, coordinate transformer 2, radar conditioner 3, radar equipment simulator 4, PVU 5, control and monitoring device 6, current coordinate calculator PL 7, hydroacoustic signal conditioner 8, GAS 9 simulator, trajectory calculator interacting aircraft 10, the adder coordinates 11, the coordinates calculator PL relative to the interacting aircraft 12, simulator SDI 13.

Target settings 1 is connected:

- to the serial connection of the coordinate transformer 2, the shaper of the radar situation 3, the simulator of radar equipment 4, PVU 5, control and monitoring devices 6;

- to the serial connection of the calculator of the current coordinates of the PL 7, the shaper of hydroacoustic signals 8, simulator equipment GAS 9;

- to the second input of the shaper of hydroacoustic signals 8;

- to the serial connection of the calculator of the trajectories of the interacting LA 10, the adder of coordinates 11, the calculator of coordinates of the submarine relative to the interacting LA 12, the simulator of SDI 13.

The second outputs of the calculator of the current coordinates of the PL 7 and the calculator of the trajectories of the interacting aircraft 10 are connected to the coordinate transformer 2.

The second output of the simulator equipment GAS 9 is connected to the simulator SOI 13.

The second input of the adder coordinates 11 is connected to the calculator of the current coordinates of the submarine 7.

The simulator equipment GAS 9 and the simulator SOI 13 are connected to the PMU 5 and the control device 6.

The target parameter setter I generates data on the target parameters (course, speed, EPR, initial coordinates, environmental state, noise situation, etc.) The coordinates of the radar landmarks (for example, resettable beacon responders, jammers) are received in a rectangular coordinate system into coordinate converter 2, where they are converted into a coordinate system in which the radar (spherical) operates. Based on these coordinates, a radar video signal is generated in the radar conditioner 3, the components of which — target pulses, signals reflected from the surface, noise, noise — depend in amplitude and duration on the relative position of the radar and the targets.

The simulated radar video signal is input into the simulator of the radar equipment 4, where it is displayed on the indicator screen. The navigator operator processes the image on the indicator using the controls of the radar equipment simulator 4, superimposes an aimed crosshair on the target marks, determining their coordinates, and, thus, enters them into the PMP 5. In parallel, the radar video signal is input into the control and monitoring device 6 for display on the control indicator.

The calculator of the current coordinates of the PL 7 at each moment of time determines the coordinates of the PL by their heading, speed and initial coordinates.

According to the calculated coordinates and parameters of the submarines coming from the target parameter setter 1, the sonar shaper 8 generates submarine noise and echo signals, sea noises, reverb signals, penetrating aircraft noises, etc. The generated sonar signal enters the simulator of the GAS 9 equipment, where it is amplified and displayed in the headset of the operator and on the GAS indicator.

Using the controls of the simulator of the GAS 9 equipment, the navigator detects the targets, classifies them, and, putting the sights on the target’s mark, determines, in this way, its coordinates and enters them into the PVU 5 to solve the problem and into the control and monitoring device 6, where the error is calculated and displayed, the determination of the coordinates of the submarine by the navigator-operator.

The coordinates of a submarine in the surface condition are entered from the calculator of the current coordinates of the submarine 7 into the coordinate converter 2, because in this state, the submarine is simultaneously a radar reference.

When solving a tactical task by a group of interacting airplanes, the calculator of the trajectories of the interacting airplanes from the data coming from the target parameter setter 1 determines the location of each of the interacting airplanes in the training area at each time point.

Because interacting aircraft are radar landmarks, these coordinates are received in coordinate transformer 2 and then processed, as described above.

In addition, the specified coordinates from the calculator of the trajectories of the interacting aircraft 10 arrive at the adder of coordinates 11, where the coordinates of the submarine from the calculator of the current coordinates of the submarine 7 arrive. The adder of coordinates 11 determines the total coordinates of the submarine and these coordinates go to the computer of coordinates of the submarine relative to the interacting aircraft 12, where at each moment of time, the position of each submarine relative to each aircraft in the coordinate system is calculated, in which it solves the problems of the PIE 5.

All sets of coordinates are sent to the SOI 13 simulator.

In accordance with the tactical problem solving modes specified by the control and control device 6, the coordinates necessary in each mode are supplied to the PLL 5. The control and control device 6 indicates the operation of the navigator-operator with the SDI equipment.

When solving the problem with one aircraft, in the control mode specified from the control and monitoring device 6, the coordinates of the submarines, determined by the navigator-operator, from the simulator of the GAS 9 equipment through the simulator of the SDI 13 go to the PVU 5.

PVU 5, processing the data coming from the simulator of radar equipment 4, simulator of GAS 9 equipment and simulator of SDI 13, solves the problem of outputting the aircraft to the point of discharge of the destruction of submarines and the time of resetting the destruction of weapons or target designation for interacting aircraft.

The proposed simulator makes it possible to simulate the operation of the radio-acoustic system of the sighting and retrieval system of the PLO group of interacting aircraft.

The radio-acoustic system of the faculty located at the LA PLO is a complex system and for its competent and operational operation requires long-term education and training of navigators-operators.

The development of a simulator of such a complex is caused by the need to reduce the time and cost of training, and to preserve the resources of military assets of the Navy Air Force.

The proposed simulator has a volume larger (about 50%) of the equipment of the prototype, but allows almost 2.5 times to reduce the volume of separate simulators of radar, ASE for each of the interacting aircraft, air defense systems, and interfacing devices with which it would be possible to simulate the operation of radio-acoustic complex PPS PLO.

State tests of a prototype simulator confirmed its positive qualities.
