Abstract

FIELD: missile guidance systems.

SUBSTANCE: in a hydroacoustic system, the coordinates and speeds of the target and interception means (IM) are determined underwater and transmitted to a defensive-offensive system (DOS), where the coordinates and speeds of the target and IM are determined, an air-underwater missile is assigned, and its data is transmitted to a control station (CS), where the missile is launched. On the missile, its coordinates and speed are determined and transmitted through the control system to the onboard control system, where the coordinates of the aiming point on the surface or underwater surface of the target are determined, the trajectory and speed of the missile's movement towards the target are calculated, and these data are transmitted to the control system, where the missile's guidance commands are generated and transmitted to the missile. In the onboard control system, the trajectories of the missile are predicted, and the coordinates of the areas where the missile may be hit and the areas where the missile may begin to evade the missile are determined. When the missile approaches these areas, the trajectories and speeds of its evasion are calculated and transmitted to the control system, where the evasion commands are generated and transmitted to the missile.

EFFECT: probability of destroying a surface target by a missile is increased.

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 while evading interception means launched by the enemy.

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 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, as well as a control station (CS) and the missile data is transmitted to the CS; a missile is launched at the CS; its current coordinates and speed are determined on the missile and transmitted through the CS 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, as well as calculates the air-underwater trajectory and the speed of the missile toward the target and transmits them to the CS; the CS generates commands to guide the missile to the target along the calculated trajectory at the calculated speed and transmits them to the missile.

However, this method does not provide protection for the missile from interception, 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 are determined, as well as its characteristic features, 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 air-submarine missile, as well as the control system, are assigned to the ONS and the missile data is transmitted to the control system;

- a missile is launched at the SU;

- the missile's current coordinates and speed are determined and transmitted through the control system 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 control system;

- the control system generates commands to guide the missile to the target along the calculated trajectory at the calculated speed and transmits them to the missile;

- in the hydroacoustic system, they detect and track missile interception means (MIM) underwater, determine their current coordinates and speeds, as well as characteristic features, and transmit them to the ONS;

- in the ONS they detect and track the SPR over water and determine their current coordinates and speeds, as well as characteristics;

- in the ONS they predict the trajectories of the SPR and determine the current coordinates of the locations of possible missile impact and the locations where it begins to evade the SPR;

- in the ONS, when the missile approaches each place where the evasion begins, the air-underwater trajectory and the speed of the missile’s evasion from the SPR and continuation of movement toward the target are calculated and transmitted to the control system;

- the control system generates commands for the missile to evade the SPR and continue moving toward the target along the calculated trajectory at the calculated speed and transmits them to the missile.

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). SPR can be air, underwater and air-underwater (in the form of missiles and torpedoes).

The missile and the SU are assigned based on their effectiveness. The coordinates and speed of the missile are determined in the onboard inertial navigation system, corrected using the global satellite navigation system.

The coordinates, speeds and characteristic features of the target and the SPR 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 and the SPR are determined in the ONS by analyzing their characteristic features.

The most vulnerable point of the target is selected as the aiming point for the missile in accordance with its characteristics. The trajectory and speed of the missile's movement to the target are calculated based on the condition of bypassing third-party objects and colliding with the aiming point at the required angle with the required speed. The coordinates and sizes of underwater third-party objects are determined in the hydroacoustic system and transmitted to the ONS.

The higher the missile speed, the higher its inertia and the lower its maneuverability. The speed-to-maneuverability ratio for a missile when evading a missile defense system is optimized by setting the speed necessary and sufficient for evasion, and when approaching a target, by setting the speed necessary and sufficient for destroying the target upon collision.

The starting points of the missile's evasion from the SPR are selected on its trajectory depending on the locations of possible missile damage - from the condition of providing the missile with sufficient time for evasion. The trajectories and velocities of evasion are calculated in a known manner (RU 2794300).

Communication between the control system and the missile on the underwater part of its trajectory is carried out in a known manner (RU 2730749). By means of the missile's transitions from one medium to another, the probability of its evasion from the SPR is increased.

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 - SU; 4 - air-underwater missile.

Links between blocks: 1-2 - current coordinates and velocity of the target, as well as its characteristic features; current coordinates and velocities of the SPR, as well as their characteristic features; 2-3 - missile data, calculated trajectory and velocity of the missile's movement toward the target, calculated trajectories and velocities of the missile's evasion from the SPR and continuation of movement toward the target; 3-2 - current coordinates and velocity of the missile; 3-4 - commands to guide the missile to the target along the calculated trajectory with the calculated velocity, commands to evade the SPR and continue movement toward the target along the calculated trajectories with the calculated velocities; 4-3 - current coordinates and velocity of the missile.
