Abstract

FIELD: weapons.

SUBSTANCE: invention relates to missile guidance systems. In hydroacoustic system coordinates and speed of target under water are determined and transmitted to defence-offensive system (DOS), where coordinates and speed of target are determined, and air-submerged missile is launched. Missile coordinates and speed are determined on missile and transmitted to DOS, where aiming point coordinates on surface or underwater surface of target are determined, missile trajectory and speed are calculated and transmitted to missile, where it is directed to target. If there is communication with DOS and the target is available from the missile, the target is tracked, its coordinates and speed are determined and transmitted to DOS. In the absence of communication with the DOS and the presence of a target in the direct vision, the missile is tracked, its coordinates and speed are determined, the calculated trajectory and speed are corrected and the missile is guided to the target. In the absence of communication with the DOS and a target in the direct line of sight, the missile calculates the target coordinates and speed, corrects the calculated trajectory and speed and guides the missile to the target.

EFFECT: higher probability of surface target destruction.

Description

The invention relates to missile guidance systems, namely to defensive-offensive systems, and can be used to destroy surface targets with air-submarine missiles with protection from radio and hydroacoustic countermeasures and the setting of combined screens.

The closest to the proposed method is the method of destroying a surface target with a missile (RU 2022128081), in which a surface target is detected and tracked above the water in a defensive-offensive system (ONS) and the current coordinates and speed of the target, as well as its characteristics, are determined; an air-underwater missile is assigned in the ONS and launched; its current coordinates and speed are determined on the missile and transmitted to the ONS; the ONS determines the current coordinates of the aiming point for the missile on the surface or underwater surface of the target, and also calculates the air-underwater trajectory and speed of the missile toward the target and transmits them to the missile; on the missile, it is guided to the target along the calculated trajectory at the calculated speed.

However, this method does not provide protection for the missile from countermeasures and screens, which reduces the likelihood 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 hydroacoustic system, a surface target is detected and tracked underwater, the current coordinates and speed of the target, as well as its characteristic features, are determined, and they are transmitted to the ONS;

- in ONS they detect and track a surface target over water and determine the current coordinates and speed of the target, as well as its characteristics;

- the ONS designates an air-submarine missile and launches it;

- the rocket's current coordinates and speed are determined and transmitted to the ONS;

- in the ONS, the current coordinates of the aiming point for a missile on the surface or underwater surface of the target are determined, and the air-underwater trajectory and speed of the missile towards the target are calculated and transmitted to the missile;

- the missile is guided to the target along the calculated trajectory at the calculated speed;

- on a missile, if there is a connection with the ONS and the target is in direct line of sight, they capture and track the target, determine its current coordinates and speed and transmit them to the ONS to refine the calculated trajectory and speed;

- on a missile, in the absence of communication with the ONS and the presence of a target in direct line of sight, they capture and track the target, determine its current coordinates and speed, adjust the calculated trajectory and speed of the missile in accordance with the current coordinates and speed of the target, and guide the missile to the target along the adjusted trajectory with the adjusted speed;

- on a missile, in the absence of communication with the ONS and a target in direct line of sight, the current coordinates and speed of the target are calculated, the calculated trajectory and speed of the missile are adjusted in accordance with the calculated current coordinates and speed of the target, and the missile is guided to the target along the adjusted trajectory with the adjusted speed.

The ONS is similar to the known one (RU 2753498). The hydroacoustic system is similar to the known one (iz.ru/news/647107). The missile is similar to the known one (naked-science.ru/community/498555).

The coordinates and speed of the rocket are determined in the onboard inertial navigation system, corrected using the global satellite navigation system.

The coordinates, speed and characteristic features of the target above water are determined at the search and tracking stations as part of the ONS, and under water - at the search and tracking stations as part of the hydroacoustic system. The characteristics of the target are determined in the ONS by analyzing its characteristic features.

The missile is assigned based on its coordinates and characteristics and the coordinates, characteristics and predicted trajectory of the target. The aiming point is chosen at the most vulnerable point of the target in accordance with its characteristics.

The missile's trajectory and speed to the target are calculated based on the condition of bypassing external objects and colliding with the aiming point at the required angle with the required speed. The coordinates and dimensions of underwater external objects are determined in the hydroacoustic system and transmitted to the ONS.

The higher the speed of the missile, the higher its inertia and lower its maneuverability. The ratio of speed and maneuverability for a missile when approaching a target is optimized by setting the speed necessary and sufficient to destroy the target upon collision.

Communication between the ONS and the missile on the underwater part of its trajectory is carried out in a known manner (RU 2730749).

There is no communication between the missile and the ONS in the case of radio countermeasures or when the missile is in the area of the screen. The target is not in the direct line of sight of the missile in the air if there is an obstacle or screen between the target and the missile, and under water - in the case of hydroacoustic countermeasures or the presence of an obstacle between the target and the missile.

The presence of a target within the missile's line of sight is determined by detecting the target using the missile's homing equipment.

In the absence of communication with the ONS and the target in direct line of sight, the coordinates and speed of the target are calculated on the missile based on the coordinates, speed and acceleration of the target at the end of the previous situation.

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

Blocks: 1 - hydroacoustic system; 2 - ONS; 3 - air-underwater missile.

Links between blocks: 1-2 - current coordinates and speed of the target, as well as its characteristic features; 2-3 - calculated trajectory and speed of the missile towards the target; 3-2 - current coordinates and speed of the missile, current coordinates and speed of the target.
