Description

SUBSTANCE: invention relates to missile and torpedo guidance systems, namely to defensive-offensive systems, and can be used to destroy underwater targets located under ice outside the range of a hydroacoustic system by missiles with a torpedo warhead.

A known method of destroying an underwater target (RU 2622051), in which a launch vehicle is launched at the control station; on the launch vehicle determine its current coordinates and transmit them to the control station; determine the coordinates of the place of immersion of the torpedo warhead (TBC) into the water and calculate the flight path of the launch vehicle to the specified location; at the control station, commands are formed to guide the launch vehicle along the calculated trajectory and transmit them to the launch vehicle; at the control station, a team is formed to separate the TBC from the launch vehicle and transmit it to the launch vehicle; determine the current coordinates of the TBC; calculate the trajectory of the TBCh; form commands for guiding the TBC along the calculated trajectory.

Closest to the present invention is a method of destroying an underwater target (RU 2535958), in which a launch vehicle is launched at the control station; on a carrier rocket and a rocket with a radio-acoustic (RGA) buoy, their current coordinates and speeds are determined; calculate the trajectory and speed of the launch vehicle and missiles with RGA buoy; form guidance commands for the launch vehicle and the rocket with the RGA buoy along the calculated trajectories with the calculated speeds; form a command to separate the RGA buoy from the rocket; on the RGA buoy separated from the missile, after immersion in water, its current coordinates are determined, the target is detected and its current coordinates are determined; determine the coordinates of the place of immersion of the TBC into the water and calculate the trajectory and speed of the flight of the launch vehicle to the specified place; form commands to guide the launch vehicle along the estimated trajectory with the estimated speed; form a command separation TBC from the launch vehicle; determine the exact current coordinates of the target.

However, such methods do not provide: - preventing missiles from colliding with third-party objects and bypassing enemy missile defense zones by missiles, since they do not take into account information about such objects and zones; - the possibility of destroying a target under the ice, since they do not provide for overcoming the thickness of the ice; - high reliability of detection and tracking of the target and high accuracy of determining its coordinates on the TBC, since they do not provide for an overview of the target from different directions; - protection of the guidance of the TBC from opposition from the target, aimed at the homing head of the TBC.

These shortcomings of the known methods reduce the probability of destroying the target.

The purpose of the invention is to increase the probability of destroying an underwater target with a missile with TBC.

The proposed method is that:

- in the defensive-offensive system (ONS), they detect and accompany a missile launched from under the ice, and determine the coordinates of the missile launch site and the characteristics of the missile and the target that launched the missile;

- in the ONS, a launch vehicle is assigned to deliver a missile with an RGA buoy and a TBC with an RGA buoy and means of overcoming the ice thickness to the target area and transmit their data to the control station;

- a launch vehicle is launched at the control station;

- on the carrier rocket and the rocket with the RGA buoy, their current coordinates and speeds are determined and transmitted through the control station to the ONS;

- in the ONS, the trajectories and flight speeds of the carrier rocket and the rocket with the RGA buoy to the rocket launch site are calculated and transmitted to the control station;

- at the control station, a command is formed to separate the rocket with the RGA buoy from the launch vehicle and transmit it to the launch vehicle;

- at the control station, commands are formed to guide the launch vehicle and the rocket with the RGA buoy along the calculated trajectories with the calculated speeds and transmit them to the launch vehicle and the rocket with the RGA buoy;

- at the control station, a team is formed to separate the RGA buoy from the rocket and transfer it to the rocket with the RGA buoy;

- on the RGA buoy, separated from the missile, after immersion in water, its current coordinates are determined, the target is detected, its current coordinates and speed are determined and transmitted through the control station to the ONS;

- in the ONS determine the coordinates of the place of immersion of the TBC into the water, and also calculate the trajectory and speed of the flight of the launch vehicle to the specified place and transmit them to the control station;

- at the control station, commands are formed to guide the launch vehicle along the estimated trajectory at the estimated speed and transmit them to the launch vehicle;

- at the control station, a team is formed to separate the TBC from the launch vehicle and transmit it to the launch vehicle;

- on the TBC they overcome the ice thickness, immerse the TBC into the water and separate the RGA buoy;

- on the RGA buoy, separated from the TBC, its current coordinates are determined, the target is detected, its current coordinates and speed are determined and transmitted through the control station to the ONS;

- in the ONS determine the exact current coordinates and speed of the target;

- on the TBC, its current coordinates and speed are determined and transmitted through the control station to the ONS;

- in the ONS, the trajectory and speed of the TBC movement to the target are calculated and transmitted to the control station;

- at the control station, commands are generated to guide the TBC along the estimated trajectory at the calculated speed and transmit them to the TBC.

The well-known method (RU 2753498) is implemented in ONS. The characteristics of the missile are determined as a result of its tracking, and the characteristics of the target are determined from them.

A launch vehicle, a rocket with an RGA buoy, TBC and RGA buoys are assigned based on their effectiveness. On a launch vehicle, TBCH and a rocket with an RGA buoy, their coordinates and speeds are determined using onboard inertial navigation systems corrected using a global satellite navigation system. On RGA buoys, their coordinates are determined using the global satellite navigation system.

The trajectories and flight speeds of the launch vehicle and the missile with the RGA buoy are calculated from the condition of preventing their collision with third-party objects and the condition of the launch vehicle bypassing the enemy's anti-missile defense zones. The command for separating the rocket with the RGA buoy from the launch vehicle is formed at the beginning of the calculated flight path of the rocket with the RGA buoy, and the command for separating the RGA buoy from the rocket is formed at the end of the calculated trajectory of its flight. The team for separating the TBC from the launch vehicle is formed at the end of the calculated flight path of the launch vehicle.

The coordinates of the place of immersion of the TBV into the water are determined from the condition of the output of the TBCh to the oncoming course with the target, and the trajectory and speed of the TBCh are calculated from the condition of effective hitting the target in accordance with its characteristics.

Overcoming the thickness of the ice, immersion of the TBC in water, separation of the RGA buoy, communication between the TBC and the control station, as well as monitoring the accuracy of pointing the TBC is carried out by known methods (RU 2707233, EN 2730749). Due to the accurate determination of the coordinates and speed of the target, the homing head on the TBC is not required.

The proposed method can be implemented in the system, the block diagram of which is shown in the drawing.

Blocks: 1 - ONS; 2 - control station; 3 - launch vehicle; 4 - rocket with RGA buoy, separated from the launch vehicle; 5 - TBC, separated from the launch vehicle; 6 - RGA buoys, separated from the rocket and TBC.
