Abstract

FIELD: guiding missiles systems.

SUBSTANCE: invention relates to missile and torpedo guidance systems. In the defensive-offensive system (DOS), a missile launched from under water is detected and accompanied, the coordinates of its launch site are determined, the characteristics of the missile and the target that launched the missile, and the target location area are determined, and a carrier rocket (CR) with a torpedo warhead (TWH) and missiles with radiohydroacoustic (RHA) buoys and transmit their data to the control station (CS), where they launch the CR. On the CR and missiles with RHA buoys, their coordinates and velocities are determined and transmitted through the CS to the DOS, where trajectories and velocities for the CR and missiles with RHA buoys are calculated and transmitted to the CS, where commands are formed to separate missiles with RHA buoys from the CR and transmit them to the CR. On the CS, commands are formed to guide the CR and missiles with RHA buoys to the target area and transmit them to the CR and missiles with RHA buoys, and also form commands to separate the RHA buoys from the missiles and transmit them to missiles with RHA buoys. On the RHA buoys, after the landing, their coordinates are determined, and also the target is detected, its coordinates and speed are determined and transmitted to the CS, where the exact coordinates and speed of the target are determined and transmitted to the DOS, where the calculation of the trajectory and speed for the CR is corrected. On the CS, a team is formed to separate the TBCH from the CR and transmit it to the CR. On the TWH, after the landing, its coordinates and speed are determined and transmitted to the CS, where the trajectory and speed for the TWH are calculated. On the CS, commands are formed to guide the TWH to the target and transmit them to the TWH.

EFFECT: probability of destroying an underwater target by a missile with a TWH increases.

Description

The invention relates to missile and torpedo guidance systems, namely to defensive-offensive systems, and can be used to destroy underwater targets with missiles with a torpedo warhead.

A known method of destroying an underwater target (RU 2513366), 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; calculate the trajectory for the launch vehicle; at the control station, commands are formed to guide the launch vehicle along the calculated trajectory to the area where the target is located and transmit them to the launch vehicle; at the control station, a team is formed to separate the torpedo warhead (TBC) from the launch vehicle at the end of the calculated trajectory and transmit it to the launch vehicle; determine the current coordinates of the TBC; at the control station, the trajectory for the TBC is calculated; 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 the launch vehicle and missiles with radio-hydroacoustic (RGA) buoys, their current coordinates and speeds are determined; calculate trajectories and speeds for the launch vehicle and missiles with RGA buoys; form commands for guiding the launch vehicle and missiles with RGA buoys along the estimated trajectories with estimated speeds to the target location area; form commands for the separation of RGA buoys from missiles at the end of the calculated trajectories; on RGA buoys, after splashdown, their current coordinates are determined; on RGA buoys, a target is detected and its current coordinates are determined; determine the exact current coordinates of the target; adjust the calculation of the trajectory and speed for the launch vehicle; form a command to separate the TBC from the launch vehicle at the end of the calculated trajectory.

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; - 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 water, and determine the coordinates of the missile launch site, the characteristics of the missile and the target that launched the missile, and the size of the target area;

- in the ONS, a launch vehicle is assigned to deliver TBCs and missiles with RGA by buoys to the target location area and transmit their data to the appropriate control station;

- a launch vehicle is launched at the control station;

- on the launch vehicle and missiles with RGA buoys, their current coordinates and speeds are determined and transmitted, through the control station, to the ONS;

- in the ONS calculate the trajectories and speeds for the launch vehicle and missiles with RGA buoys and transmit them to the control station;

- at the control station, teams are formed to separate missiles with RGA buoys from the launch vehicle at the beginning of the calculated trajectories and transmit them to the launch vehicle;

- at the control station, commands are formed to guide the launch vehicle and missiles with RGA buoys along the calculated trajectories with estimated speeds to the target location area and transmit them to the launch vehicle and missiles with RGA buoys;

- at the control station, teams are formed to separate RGA buoys from missiles at the end of the calculated trajectories and transmit them to missiles with RGA buoys;

- on RGA buoys, after splashdown, their current coordinates are determined;

- on the RGA buoys, they detect the target, determine its current coordinates and speed and transmit them to the control station;

- at the control station, the exact current coordinates and speed of the target are determined and transmitted to the ONS;

- in the ONS, the calculation of the trajectory and speed for the launch vehicle is corrected;

- at the control station, a command is formed to separate the TBC from the launch vehicle at the end of the calculated trajectory and transmit it to the launch vehicle;

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

- at the control station calculate the trajectory and speed for the TBC;

- at the control station, commands are formed to guide the TBC along the estimated trajectory at the estimated speed to the target 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. The size of the target location area is determined based on the maximum speed of the target and the maximum time required to destroy it after the detection of a missile launch.

The launch vehicle, TBCH and missiles with RGA buoys are assigned based on their effectiveness. On the launch vehicle, TBCH and missiles with RGA buoys, their coordinates and speeds are determined using onboard inertial navigation systems corrected using the global satellite system. On RGA buoys, their coordinates are determined using the global satellite navigation system.

The trajectories and velocities for the launch vehicle and missiles with RGA buoys are calculated based on the need to prevent their collision with third-party objects and the need for the launch vehicle to bypass the enemy's anti-missile defense zones. The number of RGA buoys and the places of their splashdown are determined based on the need to cover the area where the target is located with the coverage areas of RGA buoys in such a way that during the movement the target is always in the coverage area of several RGA buoys - for its review from different directions.

The connection between the TBC and the control station, as well as the control of the accuracy of pointing the TBC is carried out by known methods (RU 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 - missiles with RGA buoys, separated from the launch vehicle; 5 - RGA buoys separated from missiles; 6 - TBC, separated from the launch vehicle.

Links between blocks: 1-2 - data of the launch vehicle, TBCH and missiles with RGA buoys, as well as calculated trajectories and speeds for the launch vehicle and missiles with RGA buoys; 2-1 - current coordinates and speeds of the launch vehicle and missiles with RGA buoys, as well as the exact current coordinates and speed of the target; 2-3 - commands for separating missiles with RGA buoys from the launch vehicle at the beginning of the calculated trajectories, commands for guiding the launch vehicle along the calculated trajectory at the estimated speed to the target location area, as well as the command for separating the TBC from the launch vehicle at the end of the calculated trajectory; 2-4 - commands for guiding missiles with RGA buoys along calculated trajectories with estimated speeds to the target location area, as well as commands for separating RGA buoys from missiles at the end of the calculated trajectories; 2-6 - command guidance TBC on the estimated trajectory with the estimated speed on the target; 3-2 - current coordinates and speeds of the launch vehicle and missiles with RGA buoys; 4-2 - current coordinates and speeds of missiles with RGA buoys; 5-2 - current coordinates and target speed; 6-2 - current coordinates and speed of TBC.
