Description

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

A known method of destruction of surface targets missiles with underwater launch (RU 2624258), which detect and accompany surface targets and determine their current coordinates; missiles are launched at the underwater control station; on missiles, their current coordinates are determined; calculate the trajectory of the missiles; form commands for guiding missiles to targets along the calculated trajectories.

Closest to the present invention is a method of destroying surface targets with missiles separated from the launch vehicle (US 7494089), in which surface targets are detected and tracked and their current coordinates are determined; launch a booster; on the carrier rocket and detachable rockets, their current coordinates are determined; determine the current coordinates of the aiming points for detachable missiles; calculate the flight trajectory of the separated missiles; command is formed to separate the missiles from the launch vehicle at the beginning of the calculated trajectories of their flight; commands are formed to point the separated missiles at the targets along the calculated trajectories and transmit them to the separated missiles.

However, such methods do not provide: - high reliability of detection and tracking of targets and high accuracy of determining their coordinates, since they do not provide for an overview of targets and their location from different directions; - preventing missiles from colliding with third-party objects and bypassing enemy missile defense zones by missiles, since they do not take into account information about such objects and zones; - optimization of the ratio of speed and maneuverability for missiles, since they do not take into account the speed of missiles and targets; - protection of missile guidance from counteraction from targets directed at missile homing heads. In addition, the proximity of the means of guiding missiles to targets to the missile launch site increases the likelihood of suppression of the means of guidance by the enemy.

These shortcomings of the known methods reduce the probability of destroying targets.

The purpose of the invention is to increase the probability of destruction of surface targets by missiles.

The proposed method is that:

- in the defensive-offensive system, they detect and accompany surface targets and determine their current coordinates and speeds;

- in the defensive-offensive system, a launch vehicle is assigned to destroy targets and a surface control station to guide the launch vehicle and detachable missiles to targets and transmit their data to the corresponding underwater control station to launch the launch vehicle;

- a launch vehicle is launched at the underwater control station;

- on the launch vehicle and detachable missiles, their current coordinates and speeds are determined and, after the launch vehicle exits from under the water, they are transmitted to the surface control station;

- from the surface control station, the current coordinates and speeds of the launch vehicle and detachable missiles are transmitted to the defensive-offensive system;

- in the defensive-offensive system, the current coordinates of the aiming points for the detachable missiles are determined;

- in the defensive-offensive system, the trajectories and flight speeds of the launch vehicle and the missiles to be separated are calculated and transmitted to the surface control station;

- at the surface control station, teams form the separation of missiles from the launch vehicle at the beginning of the calculated trajectories of their flight and transmit them to the launch vehicle;

- at the surface 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.

In the defensive-offensive system, a known method is implemented (RU 2753498). Surface targets can also be ground, air or space targets. In a defensive-offensive system, a launch vehicle for destroying targets and a surface control station for guiding the launch vehicle and missiles to targets are assigned based on their effectiveness.

The communication of the defensive-offensive system and the underwater control station is carried out in a known manner (RU 2666904). At the underwater control station, the surface control station data received from the defensive-offensive system is transmitted to the launch vehicle and missiles for their connection with the surface control station.

At the underwater control station, its coordinates and speed are determined in a known manner (RU 2737166). On the launch vehicle and rockets, their coordinates and speeds are determined using onboard inertial navigation systems corrected using the global satellite navigation system.

In a defensive-offensive system, the coordinates of aiming points for missiles are determined by selecting the most vulnerable target locations based on information obtained using search and tracking stations as a result of reviewing targets and their area from various directions.

In a defensive-offensive system, the trajectory and flight speed of the launch vehicle and missiles are calculated based on the need to prevent their collision with third-party objects and with each other, the need for the launch vehicle to bypass the enemy’s anti-missile defense areas and the need for missiles to collide with aiming points under the required angles at the required speeds. The higher the speed of missiles, the higher their inertia and lower maneuverability. The ratios of speed and maneuverability for missiles in the final sections of the calculated trajectories are optimized by setting the design speeds necessary and sufficient to destroy targets in a collision.

At the surface control station, commands for the separation of missiles from the launch vehicle are formed when the coordinates of the missiles coincide with the coordinates of the beginning of the calculated trajectories of their flight, and the commands for aiming the launch vehicle and missiles at targets along the calculated trajectories with the calculated speeds are formed in a known way (RU 2537124).

Through the use of a defensive-offensive system, they provide protection for missile guidance from counteraction from targets, since missiles do not require homing heads, and also reduce the likelihood of suppression of missile guidance means on targets by the enemy, since the guidance means are removed from the launch site of the launch vehicle.

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

Blocks: 1 - defensive-offensive system; 2 - underwater control station; 3 - surface control station; 4 - launch vehicle with detachable missiles launched from an underwater control station; 5 - rockets separated from the launch vehicle.

Connections between blocks: 1-2 - data of the launch vehicle assigned to destroy targets, and the surface control station assigned to guide the launch vehicle and detachable missiles to the target; 1-3 - calculated trajectories and flight speeds of the launch vehicle and rockets to be separated; 3-1 - current coordinates and velocities of the launch vehicle and rockets to be separated; 3-4 - commands for separating missiles from the launch vehicle at the beginning of the calculated trajectories of their flight, as well as commands for guiding the launch vehicle with detachable missiles to targets along the calculated trajectory at the estimated speed; 3-5 - guidance commands for missiles separated from the launch vehicle at targets along calculated trajectories with estimated speeds; 4-3 - current coordinates and speed of the launch vehicle with detachable missiles; 5-3 - current coordinates and speeds of rockets separated from the launch vehicle.
