Abstract

FIELD: weapons.

SUBSTANCE: invention relates to missile guidance systems. Coordinates, speeds and characteristics of targets are determined in a defensive-offensive system (DOS). Coordinates and velocities thereof on the objects are determined and transmitted to the DOS, where the trajectory of targets and objects is determined and their continuation is predicted. In DOS determining the aiming points coordinates, predicting the debris trajectories and velocities during the missile collision with the aiming point at each target trajectory continuation point, determining each target destruction points coordinates with minimum probability of damage to objects by debris, determining each target destruction site coordinates and time, carrier rocket (CR) and control station (CS) are assigned and CR data are transmitted to CS, where CR is launched. On CR and missiles their coordinates and speeds are determined and transmitted via CS to DOS, where trajectories and velocities of CR and missiles are calculated and transmitted to CS, where commands for separation of missiles from CR and guiding CR and missiles to targets are generated and transmitted to CR and missiles.

Description

The invention relates to missile guidance systems, namely to defensive-offensive systems, and can be used to destroy groups of targets by groups of missiles separated from launch vehicles, with a minimum probability of causing damage to their objects by debris formed during the destruction of targets.

The closest to the proposed method is the destruction of targets by missiles separating from the launch vehicle (RU 2777874), where the defensive-offensive system (ONS) detects and tracks targets and determines the current coordinates and velocities of targets, as well as their characteristics; the ONS determines the trajectories of targets and predicts their continuation; the ONS determines the current coordinates of the aiming points for missiles; the ONS assigns a launch vehicle (LV) and a control station (CS) to destroy targets and transmits LV data to the CS; the CS launches the LV; the LV and separable missiles determine their current coordinates and velocities and transmits them through the CS to the ONS; the ONS calculates the trajectories and velocities of the LV and separable missiles toward the targets and transmits them to the CS; the CS generates commands for separating missiles from the LV at the beginning of the calculated trajectories and transmits them to the LV; At the control system, commands are generated to guide the launch vehicle and separated missiles to targets along calculated trajectories with calculated speeds and transmitted to the launch vehicle and separated missiles.

However, this method has a high probability of causing damage to one's own objects from debris generated during the destruction of targets, due to the lack of an analysis of the possible consequences of the destruction of targets for the environment.

The purpose of the invention is to reduce the likelihood of damage to one's own objects from debris generated during the destruction of targets.

The proposed method is that:

- in the ONS they detect and track targets and determine the current coordinates and speeds of targets, as well as their characteristics;

- determine their current coordinates and speeds at their facilities and transmit them to the ONS;

- in the ONS they determine the trajectories of targets, as well as the trajectories of their objects, and predict their continuation;

- in the ONS, the current coordinates of the aiming points for missiles are determined;

- in the ONS, they predict the trajectories and speeds of movement of the debris that are formed when a missile collides with an aiming point at each location of the continuation of the trajectory of each target;

- in the ONS, the coordinates of the destruction sites of each target are determined, in which the probability of causing damage to one’s own objects by debris is minimal, along the continuation of the trajectory of each target;

- in the ONS, the current coordinates of the destruction location of each target along its trajectory and the time of the target’s appearance there are determined;

- the ONS assigns the RN and SU to destroy targets and transmits the RN data to the SU;

- the launch vehicle is launched at the SU;

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

- the ONS calculates the trajectories and speeds of the launch vehicles and separated missiles to the targets and transmits them to the control system;

- the control system generates commands for separating missiles from the launch vehicle at the beginning of the calculated trajectories and transmits them to the launch vehicle;

- the control system generates commands for guiding the launch vehicle and separated missiles to targets along calculated trajectories with calculated speeds and transmits them to the launch vehicle and separated missiles.

The ONS is similar to the known one (RU 2753498). Targets can be air or space, and objects can be ground, surface, air or space. The coordinates and speeds of targets are determined as a result of their survey from various directions, and the characteristics of targets - as a result of their tracking. The coordinates and speeds of their objects are determined in onboard inertial navigation systems, corrected using the global satellite navigation system.

Aiming points for missiles are selected in the most vulnerable places of targets in accordance with their characteristics. Trajectories and velocities of fragments are predicted based on the results of modeling the process of destruction of targets by missiles (vestnikmai.ru/publications.php?ID=78871). The probability of causing damage to friendly objects by fragments is determined by comparing the predicted trajectories and velocities of fragments with the continuation of trajectories and velocities of friendly objects. The places of destruction of targets are selected from among the places with the minimum probability of causing damage to friendly objects by fragments, provided that the launch vehicle has enough time to separate the missiles and destroy the targets.

The coordinates and speeds of the launch vehicles and missiles are determined in onboard inertial navigation systems, adjusted using the global satellite navigation system. The trajectories and speeds of the launch vehicles and missiles to their targets are calculated based on the condition that they bypass third-party objects and, if possible, the enemy's anti-missile defense zones, as well as on the condition that the missiles collide with the aiming points at the required angles and speeds.

After the missiles are separated from the launch vehicle, the redistribution of targets between them is carried out by adjusting the calculated trajectories and velocities of the missiles. The higher the speed of the missiles, the higher their inertia and the lower their maneuverability. The ratio of speed and maneuverability for missiles at the final section of their trajectories is optimized by setting the speeds necessary and sufficient to destroy the targets upon collision.

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

Blocks: 1 - ONS; 2 - own objects; 3 - SU; 4 - LV with detachable missiles; 5 - missiles separated from the LV.

Links between blocks: 1-3 - launch vehicle data, as well as calculated trajectories and speeds of the launch vehicle and detachable missiles toward targets; 2-1 - current coordinates and speeds of friendly objects; 3-1 - current coordinates and speeds of the launch vehicle and detachable missiles, as well as current coordinates and speeds of the separated missiles; 3-4 - commands to separate missiles from the launch vehicle at the beginning of calculated trajectories, as well as commands to guide the launch vehicle to targets along a calculated trajectory with a calculated speed; 3-5 - commands to guide separated missiles to targets along calculated trajectories with calculated speeds; 4-3 - current coordinates and speeds of the launch vehicle and detachable missiles; 5-3 - current coordinates and speeds of separated missiles.
