Description

The invention relates to missile guidance systems, namely to defensive-offensive systems, and can be used to destroy surface targets with missiles launched from under water.

There is a method of destroying a surface target with a rocket (RU 2382313), in which a surface target is detected and accompanied and its current coordinates are determined; launch a rocket; determine the current coordinates of the rocket; form commands for aiming the missile at the target.

Closest to the present invention is a method of destroying a surface target with a missile launched from under water (RU 2624258), in which a surface target is detected and tracked and its current coordinates are determined; a rocket is launched at an underwater control station; on the rocket determine its current coordinates; calculate the trajectory of the rocket; commands are formed to guide the missile to the target along the calculated trajectory.

However, such methods do not provide: - high reliability of detection and tracking of the target and high accuracy of determining its coordinates, since they do not provide for the review of the target from different directions; - preventing a missile from colliding with third-party objects and bypassing the enemy's anti-missile defense zones by the missile, since they do not take into account information about such objects and zones; - optimization of the ratio of speed and maneuverability for a rocket, since they do not take into account the speed of the rocket and the target; - protection of missile guidance from opposition from the target, directed at the missile's homing head. In addition, the proximity of the means of guiding the missile to the target to the missile launch site increases the likelihood of suppression of the means of guidance by the enemy.

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 a surface target with a missile.

The proposed method is that:

- in a defensive-offensive system, they detect and accompany a surface target and determine its current coordinates and speed;

- in the defensive-offensive system, a missile is assigned to destroy the target and a surface control station to guide the missile to the target and transmit their data to the corresponding underwater control station to launch the missile;

- a missile is launched at the underwater control station;

- on the rocket, its current coordinates and speed are determined and, after the rocket leaves the water, they are transmitted to the surface control station;

- from the surface control station, the current coordinates and speed of the missile are transmitted to the defensive-offensive system;

- in the defensive-offensive system, the current coordinates of the aiming point for the missile are determined;

- in the defensive-offensive system, the trajectory and speed of the missile are calculated and transmitted to the surface control station;

- at the surface control station, commands are formed to aim the missile at the target along the calculated trajectory at the calculated speed and transmit them to the missile.

In the defensive-offensive system, a known method is implemented (RU 2753498). The surface target can also be ground, air or space. In a defensive-offensive system, a missile to destroy a target and a surface control station to guide the missile to the target are assigned based on their effectiveness.

Communication defensive-offensive system and underwater control station is carried out in a known manner (RU 2666904). At the underwater control station, the surface control station data received from the defensive-offensive system is transmitted to the missile for its connection with the surface control station.

At the underwater control station, its coordinates and speed are determined in a known manner (RU 2737166). On the rocket, its coordinates and speed are determined using an onboard inertial navigation system corrected using a global satellite navigation system.

In a defensive-offensive system, the coordinates of the aiming point for a missile are determined by selecting the most vulnerable target site based on information obtained using search and tracking stations as a result of target review from various directions.

In a defensive-offensive system, the trajectory and flight speed of a missile is calculated based on the need to prevent its collision with third-party objects, the need for the missile to bypass the enemy's anti-missile defense zones, and the need for the missile to collide with the aiming point at the required angle at the required speed. The higher the rocket speed, the higher its inertia and lower maneuverability. The ratio of speed and maneuverability for a missile in the final section of the calculated trajectory is optimized by setting the estimated speed necessary and sufficient to destroy the target in a collision.

At the surface control station, commands for aiming the missile at the target along the estimated trajectory with the estimated speed are formed in a known manner (RU 2537124).

Through the use of a defensive-offensive system, they provide protection for missile guidance from counteraction from the target, since the missile does not require a homing head, and also reduce the likelihood of enemy suppression of missile guidance means at the target, since the guidance means are removed from the missile launch site.

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

Blocks: 1 - defensive-offensive system; 2 - underwater control station; 3 - surface control station; 4 - a missile launched from an underwater control station.

Connections between blocks: 1-2 - data of the missile assigned to destroy the target, and the surface control station assigned to guide the missile to the target; 1-3 - calculated trajectory and speed of the rocket; 3-1 - current coordinates and speed of the rocket; 3-4 - commands to aim the missile at the target along the estimated trajectory with the estimated speed; 4-3 - current coordinates and rocket speed.
