In the hydroacoustic system, underwater targets are detected and tracked, their coordinates, speeds and characteristics are determined and they are transmitted to the defensive-offensive system (DOS), where the trajectories of targets and the coordinates of the place and the time of their exit from under the water are determined, as well as the coordinates of the place and time the launch vehicle (LV) on a collision course, the LV is assigned and its data is transmitted to the control station, where the LV is launched. On the LV and missiles, their coordinates and speeds are determined and transmitted through the control station to the DOS, where the trajectory and flight speed of the LV to the place where they enter the oncoming course are calculated and transmitted to the control station, where the LV guidance commands are formed and transmitted to the LV.

Description

SUBSTANCE: invention relates to missile guidance systems, namely to defensive-offensive systems, and can be used to destroy group targets with a deep-water launch by groups of missiles separated from launch vehicles.

Closest to the proposed method is the destruction of targets by missiles separated from the launch vehicle (RU 2769168), in which the launch vehicle (LV) and the control station are assigned in the defensive-offensive system (ONS), and the LV data is transmitted to the control station ; at the control station launch the launch vehicle; on the launch vehicle and detachable missiles, their current coordinates and speeds are determined and transmitted through the control station to the ONS; in the ONS they detect and track targets and determine the exact current coordinates and speeds of targets, as well as their exact characteristics; in the ONS determine the current coordinates of the aiming points for the detachable missiles, and also calculate the trajectories and flight speeds of the launch vehicle and the detachable missiles to the targets and transmit them to the control station; at the control station, teams are formed to separate the missiles from the launch vehicle at the beginning of the calculated trajectories and transmit them to the launch vehicle; at the control station, commands are formed to guide the launch vehicle and the separated missiles to the target along the calculated trajectories with the calculated speeds and transmit them to the launch vehicle and the separated missiles.

However, this method does not provide: does not provide for the analysis of the underwater part of the target trajectories; - the output of the launch vehicle on a collision course.

These shortcomings of the known method reduce the probability of destruction of targets.

The purpose of the invention is to increase the probability of destroying targets with deep-sea launch missiles.

The proposed method is that:

- in the hydroacoustic system, underwater targets are detected and tracked, the current coordinates and speeds of the targets, as well as their characteristics, are determined, and they are transmitted to the ONS;

- in the ONS they determine the trajectories of targets, predict their continuation and determine the current coordinates of the place and the time of the exit of the targets from under the water, as well as the current coordinates of the place and the time of the launch of the launch vehicle on a collision course;

- in the ONS, a launch vehicle is assigned, as well as a control station, and the data of the launch vehicle is transmitted to the control station;

- LV is launched at the control station;

- on the launch vehicle and detachable missiles, their current coordinates and speeds are determined and transmitted through the control station to the ONS;

- in the ONS calculate the trajectory and speed of the LV flight to the place of entry into the oncoming course and transmit them to the control station;

- at the control station, commands are generated for guiding the launch vehicle to the place where it enters the oncoming course along the estimated trajectory at the calculated speed and transmit them to the launch vehicle;

- in the ONS, after the targets exit from under the water, they detect and accompany the targets and determine the exact current coordinates and speeds of the targets, as well as their exact characteristics;

- in the ONS, after the launch vehicle enters the oncoming course, the current coordinates of the aiming points for the detachable missiles are determined, and the trajectories and flight speeds of the launch vehicle and the detachable missiles to the targets are calculated and transmitted to the control station;

- at the control station, teams are formed to separate the missiles from the launch vehicle at the beginning of the calculated trajectories and transmit them to the launch vehicle;

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

The hydroacoustic system is similar to the known one (iz.ru/news/647107). The targets are similar to the Skif missile (www.gazeta.ru/army/2021/12/29/14372341.shtml). The coordinates and speeds of targets are determined as a result of a review of their location from different directions, and the characteristics of the targets are determined as a result of their tracking. ONS is similar to the known one (RU 2753498). The place and time of the launch of the launch vehicle on a collision course is chosen on the axis of the predicted continuation of the trajectories of the targets from the condition of providing the launch vehicle with time sufficient to separate the missiles and destroy the targets shortly after they leave the water.

Launch vehicles, missiles and a control station are assigned based on their effectiveness. On launch vehicles and missiles, their coordinates and speeds are determined using onboard inertial navigation systems, corrected using a global satellite navigation system.

The trajectory and flight speed of the launch vehicle to the place where it enters the oncoming course is calculated from the condition of bypassing the launch vehicle of third-party objects and the enemy's anti-missile defense zones. The coordinates of aiming points for missiles are determined by selecting the most vulnerable targets in accordance with their characteristics. Trajectories and flight speeds of launch vehicles and missiles to targets are calculated from the condition of collision of missiles with aiming points at the required angles with the required speeds. After the missiles are separated from the launch vehicle, the redistribution of targets between them is carried out by correcting their calculated trajectories and velocities.

The higher the speed of missiles, the higher their inertia and lower maneuverability. The ratio of speed and maneuverability for missiles in the final sections of the trajectories is optimized by setting the speeds necessary and sufficient to destroy targets 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 - launch vehicle with detachable missiles; 5 - missiles separated from the launch vehicle.

Connections between blocks: 1-2 - current coordinates and speeds of targets, as well as their characteristics; 2-3 - LV data, estimated trajectory and flight speed of the LV to the place where it enters the oncoming course, as well as the calculated trajectories and flight speeds of the LV and the missiles to be separated to the targets; 3-2 - current coordinates and speeds of the launch vehicle and missiles to be separated; 3-4 - commands for guiding the launch vehicle to the place of entry into the oncoming course along the calculated trajectory at the calculated speed, commands for separating missiles from the launch vehicle at the beginning of the calculated trajectories, as well as commands for guiding the launch vehicle to targets along the calculated trajectory at the calculated speed; 3-5 - commands to guide the separated missiles to the target along the calculated trajectories with the calculated speeds; 4-3 - current coordinates and velocities of the launch vehicle and detachable missiles; 5-3 - current coordinates and speeds of missiles separated from the launch vehicle.
