Abstract

FIELD: missile guidance systems.

SUBSTANCE: invention relates to missile guidance systems, namely to defensive-offensive systems. In the hydroacoustic system, an underwater target is detected and tracked, its coordinates, speed and characteristics are determined and transmitted to the defensive-offensive system (DOS), where the target’s trajectory and the coordinates of the place and the time of its exit from under the water are determined, as well as the coordinates of the place and time when the missile enters a collision course, the missile is assigned and its data is transmitted to the control station, where the missile is launched. On the rocket, its coordinates and speed are determined and transmitted through the control station to the DOS, where the trajectory and flight speed of the rocket to the point of entry into the oncoming course are calculated and transmitted to the control station, where the missile guidance commands are formed and transmitted to the rocket. In the DOS, after the target exits from under the water, they detect and accompany the target and determine its coordinates, speed and characteristics, and after the missile enters the oncoming course, they determine the coordinates of the aiming point, and also calculate the trajectory and speed of the missile to the target and transmit them to the control station, where missile guidance commands are formed and transmitted to the missile.

EFFECT: method provides an increase in the probability of destroying a target with a deep-sea rocket launch.

Description

The invention relates to missile guidance systems, namely to defensive-offensive systems, and can be used to destroy targets with deep-water missile launch.

Closest to the proposed method is a method of destroying a target with a rocket (RU 2768062), in which the trajectory of the target is determined in the defensive-offensive system (ONS), its continuation is predicted and the current coordinates of the exit point of the missile on a collision course are determined; in the ONS, a rocket is assigned, as well as a control station, and the rocket data is transmitted to the control station; a rocket is launched at the control station; on the rocket, its current coordinates and speed are determined and transmitted through the control station to the ONS; in the ONS calculate the trajectory and speed of the missile to the place of entry into the collision course and transmit them to the control station; at the control station, commands are formed to guide the rocket to the place of exit to the oncoming course along the calculated trajectory at the calculated speed and transmit them to the rocket; in the ONS they detect and accompany the target, determine the exact current coordinates and speed of the target, as well as its exact characteristics; in the ONS, after the missile enters the oncoming course, the current coordinates of the aiming point for the missile are determined, and the trajectory and speed of the missile to the target are calculated and transmitted to the control station; at the 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.

However, this method does not ensure that the missile approaches the target shortly after it leaves the water, because does not provide for the analysis of the underwater part of the target's trajectory, which reduces the likelihood of its destruction.

The purpose of the invention is to increase the probability of destroying a target with a deep-sea rocket launch.

The proposed method is that:

- in the hydroacoustic system, they detect and accompany an underwater target, determine the current coordinates and speed of the target, as well as its characteristics, and transmit them to the ONS;

- in the ONS they determine the trajectory of the target, predict its continuation and determine the current coordinates of the place and the time of the exit of the target from under the water, as well as the current coordinates of the place and the time of the exit of the missile on a collision course;

- a rocket is assigned to the ONS, as well as a control station, and the rocket data is transmitted to the control station;

- a rocket is launched at the control station;

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

- in the ONS calculate the trajectory and speed of the missile to the place of entry into the collision course and transmit them to the control station;

- at the control station, commands are formed to guide the rocket to the place where it enters the oncoming course along the calculated trajectory at the calculated speed and transmit them to the rocket;

- in the ONS, after the target exits from under the water, they detect and accompany the target, determine the exact current coordinates and speed of the target, as well as its exact characteristics;

- in the ONS, after the missile enters the oncoming course, the current coordinates of the aiming point for the missile are determined, and the trajectory and speed of the missile to the target are calculated and transmitted to the control station;

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

The hydroacoustic system is similar to the known one (iz.ru/news/647107). The target is similar to the Skif missile (www.gazeta.ru/army/2021/12/29/14372341.shtml). The coordinates and speed of the target are determined as a result of its review from various directions, and the characteristics of the target are determined as a result of its tracking. ONS is similar to the known one (RU 2753498). The place and time of the missile entering the counter course is chosen on the predicted continuation of the target trajectory from the condition of providing the missile with time sufficient to destroy the target shortly after it leaves the water.

A missile and a control station are assigned based on their effectiveness. On the rocket, its coordinates and speed are determined using an onboard inertial navigation system corrected using a global satellite navigation system.

The trajectory and speed of the missile's flight to the place where it enters the oncoming course is calculated from the condition of the missile bypassing third-party objects and the enemy's anti-missile defense zones. The coordinates of the aiming point for the missile are determined by selecting the most vulnerable spot of the target in accordance with its characteristics. The trajectory and speed of the missile to the target is calculated from the condition of the collision of the missile 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 trajectory is optimized by setting the speed necessary and sufficient to destroy the target in a collision.

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

Blocks: 1 - hydroacoustic system; 2 - ONS; 3 - control station; 4 - rocket.

Connections between blocks: 1-2 - current coordinates and speed of the target, as well as its characteristics; 2-3 - missile data, the estimated trajectory and speed of the missile to the place of entry into the oncoming course, as well as the estimated trajectory and speed of the missile to the target; 3-2 - current coordinates and speed of the rocket; 3-4 - commands for guiding the missile to the place of entry into the oncoming course along the calculated trajectory at the calculated speed, as well as commands for guiding the missile to the target along the calculated trajectory at the calculated speed; 4-3 - current coordinates and rocket speed.
