Description

The invention relates to missile guidance systems, namely defensive-offensive systems, and can be used to destroy group high-speed air-submarine targets maneuvering relative to the surface of the water by groups of air-submarine missiles separated from the launch vehicles.

The closest to the proposed method is the method of destroying high-speed maneuvering targets with missiles separated from the launch vehicle (RU 2777874), where in the defensive-offensive system (ONS) targets are detected and tracked and the current coordinates and speeds of targets are determined, as well as their characteristics; in the ONS they determine the trajectory of targets, relative to which they maneuver and predict its continuation; in the ONS, the current coordinates of the launch vehicle (LV) exit point are determined; the ONS assigns a launch vehicle with missiles, as well as a control station (CS), and transmits the launch vehicle data to the control center; the launch vehicle is launched on the control system; on launch vehicles and missiles, their current coordinates and velocities are determined and transmitted through the control system to the ONS; in the ONS, the trajectory and speed of the LV movement to the point of entering the oncoming course are calculated and transmitted to the control system; on the control system, commands are generated to guide the launch vehicle to the point of entering the oncoming course along the calculated trajectory at the design speed and transmit them to the launch vehicle; in the ONS, after the launch vehicle is on a collision course, they determine the current coordinates of the aiming points for the missiles, and also calculate the trajectories and speeds of the launch vehicle and missiles towards the targets and transmit them to the control system; commands are generated at the control system for separating missiles from the launch vehicle at the beginning of the calculated trajectories and transmit them to the launch vehicle; on the control system, commands are generated to guide the launch vehicle and separated missiles to targets along calculated trajectories with calculated speeds and transmit them to the launch vehicle and separated missiles.

However, this method does not provide visibility of the underwater space and the ability for missiles to approach targets under water, which reduces the likelihood of destroying air-submarine targets.

The purpose of the invention is to increase the likelihood of destroying air-submarine targets with missiles.

The proposed method is that:

- the ONS detects and tracks air-submarine targets on the air part of their trajectories and determines the current coordinates and speeds of targets, as well as their characteristics;

- in the hydroacoustic system, they detect and track air-underwater targets on the underwater part of their trajectories, determine the current coordinates and speeds of the targets, as well as their characteristics, and transmit them to the ONS;

- in the ONS they determine the trajectory of targets, relative to which they maneuver, predict its continuation and project it onto the surface of the water;

- in the ONS, the current coordinates of the place where the launch vehicle enters the oncoming course are determined above the projection of the continuation of the target trajectory;

- the ONS assigns a launch vehicle with air-submarine missiles, as well as a control system, and transmits the launch vehicle data to the control system;

- the launch vehicle is launched on the control system;

- on launch vehicles and missiles, their current coordinates and velocities are determined and transmitted through the control system to the ONS;

- the ONS calculates the trajectory and speed of the launch vehicle to the point where it enters the oncoming course and transmits them to the control system;

- on the control system, commands are generated to guide the launch vehicle to the point of entering the oncoming course along the calculated trajectory at the design speed and transmit them to the launch vehicle;

- in the ONS, after the launch vehicle is on a collision course, the current coordinates of the aiming points for the missiles are determined, as well as the trajectories and speeds of the launch vehicle and missiles towards the targets are calculated and transmitted to the control system;

- commands are generated at the control system for separating missiles from the launch vehicle at the beginning of the design trajectories and transmit them to the launch vehicle;

- on the control system, commands are formed to guide the launch vehicle and separated missiles to targets along calculated trajectories with calculated speeds and transmit them to the launch vehicle and separated missiles.

ONS is similar to the well-known one (RU 2753498). The hydroacoustic system is similar to the well-known one (iz.ru/news/647107). The targets and missiles are similar to the well-known one (naked-science.ru/community/498555). The coordinates and speeds of targets are determined as a result of their viewing from various directions, and the characteristics of targets are determined as a result of their tracking. The trajectory of targets relative to which they maneuver is determined based on an analysis of their actual trajectories. The location where the launch vehicle enters the oncoming course is selected from the condition of providing the launch vehicle with enough time to separate the missiles and destroy targets.

The coordinates and speeds of launch vehicles and missiles are determined in on-board inertial navigation systems, corrected using a global satellite navigation system.

The trajectory and speed of the launch vehicle's movement to the point where it enters the oncoming course is calculated from the condition of the launch vehicle bypassing third-party objects and, if possible, enemy missile defense coverage areas. The coordinates and sizes of underwater third-party objects are determined in the hydroacoustic system and transmitted to the ONS. The coordinates of aiming points for missiles are determined by selecting the most vulnerable spots of targets in accordance with their characteristics. The trajectories and speeds of movement of launch vehicles and missiles towards targets are calculated from the condition of missiles colliding with aiming points at the required angles with the required speeds. After the missiles are separated from the launch vehicle, targets are redistributed between them by adjusting their calculated trajectories and speeds.

The higher the speed of the missiles, the higher their inertia and the lower their maneuverability. The ratio of speed and maneuverability for missiles in the final part of their trajectories is optimized by setting speeds necessary and sufficient to destroy targets in the event of a collision. Communication between the control system and missiles on the underwater part of their trajectories is carried out in a known manner (RU 2730749).

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 - launch vehicle with air-submarine missiles; 5 - air-submarine missiles separated from the launch vehicle.

Connections between blocks: 1-2 - current coordinates and velocities of targets, as well as their characteristics; 2-3 - LV data, calculated trajectory and speed of the LV to the point of entering the oncoming course, calculated trajectories and speed of the LV and missiles to the targets; 3-2 - current coordinates and velocities of launch vehicles and missiles; 3-4 - commands for guiding the launch vehicle to the point of entering the oncoming course along the calculated trajectory with the design speed, commands for separating the missiles from the launch vehicle at the beginning of the design trajectories, commands for guiding the launch vehicle to the targets along the design trajectory with the design speed; 3-5 - commands for guiding separated missiles to targets along calculated trajectories with calculated speeds; 4-3 - current coordinates and velocities of launch vehicles and missiles; 5-3 - current coordinates and velocities of missiles separated from the launch vehicle.
