Abstract

FIELD: military equipment.

SUBSTANCE: in a defensive-offensive system (DOS), the coordinates and speed of the target are determined, and a target destruction means (TDM) is launched, where its coordinates and speed are determined and transmitted to the DOS, where the trajectory and speed of the TDM are calculated and the TDM is aimed at the target. If there is a connection between the DOS and the target in direct line of sight, the target is tracked, its coordinates and speed are determined, and transmitted to the DOS. In the absence of communication with the DOS and the presence of a target in direct line of sight, the target is tracked, its coordinates and speed are determined, the calculated trajectory and speed are adjusted, and the target is aimed at the target. In the absence of communication with the DOS and the presence of a target in direct line of sight, the target's coordinates and speed are calculated, the calculated trajectory and speed are adjusted, and the target is aimed at the target.

EFFECT: this increases the probability of target destruction.

Description

The invention relates to military equipment, namely to defensive-offensive systems, and can be used to protect weapons with command and homing guidance to targets from radio and hydroacoustic countermeasures and the setting of combined screens.

There are known countermeasures and screening devices (RU 2610792, RU 2736660, RU 2809997) that suppress the control and navigation channels of weapons with command and homing on targets, which reduces the probability of destroying targets. At the same time, the methods of protecting such weapons from countermeasures and screening are unknown.

The purpose of the invention is to increase the probability of destroying a target with a means of destruction.

The proposed method is that:

- in the defensive-offensive system (ONS), they detect and track the target and determine its current coordinates and speed, as well as characteristics;

- in the ONS, a target destruction means (TDM) is designated and launched;

- the SPC determines its current coordinates and speed and transmits them to the ONS;

- in the ONS, the current coordinates of the aiming point for the SPC on the target surface are determined, and the trajectory and speed of the SPC movement to the target are calculated and transmitted to the SPC;

- at the SPC they guide it to the target along the calculated trajectory at the calculated speed;

- at the SPC, if there is a connection with the ONS and the target is in direct line of sight, they capture and track the target, determine its current coordinates and speed and transmit them to the ONS to clarify the calculated trajectory and speed;

- at the SPC, in the absence of communication with the ONS and the presence of a target in direct line of sight, they capture and track the target, determine its current coordinates and speed, adjust the calculated trajectory and speed of the SPC in accordance with the current coordinates and speed of the target and guide the SPC to the target along the adjusted trajectory with the adjusted speed;

- at the SPC, in the absence of communication with the ONS and the target in direct line of sight, the current coordinates and speed of the target are calculated, the calculated trajectory and speed of the SPC are adjusted in accordance with the calculated current coordinates and speed of the target, and the SPC is guided to the target along the adjusted trajectory with the adjusted speed.

The ONS is similar to the known one (RU 2753498). The target can be underground, underwater, ground, surface, air and space (in the form of a military object, weapon system, missile, torpedo and laser). The SPC can be underwater, air and space (in the form of a missile, torpedo and laser).

The coordinates and speed of the SPC are determined in the onboard inertial navigation system, corrected using the global satellite navigation system.

The coordinates, speed and characteristic features of the target above the earth's surface are determined at search and tracking stations as part of the ONS, underwater - at search and tracking stations as part of the hydroacoustic system (iz.ru/news/647107), and underground - using ground penetrating radars (US 7948829), and transmitted to the ONS. The characteristics of the target are determined in the ONS by analyzing its characteristic features.

The SPC is assigned based on its coordinates and characteristics and the coordinates, characteristics and predicted trajectory of the target. The aiming point is selected in the most vulnerable place of the target in accordance with its characteristics.

The trajectory and speed of the SPC movement to the target are calculated based on the condition of its bypassing third-party objects and the SPC collision 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 speed of the SPC, the higher its inertia and lower its maneuverability. The speed-to-maneuverability ratio for the SPC when approaching a target is optimized by setting the speed necessary and sufficient to destroy the target upon collision.

There is no connection between the SPC and the ONS in the event of radio countermeasures or when the SPC is in the area of the screen. The target is not in the direct line of sight of the SPC in the air if there is an obstacle or screen between the target and the SPC, and under water - in the event of hydroacoustic countermeasures or an obstacle between the target and the SPC.

The presence of a target within the direct line of sight of the SPC is determined by detecting the target using the SPC's homing means.

In the absence of communication with the ONS and the target in direct line of sight, the coordinates and speed of the target are calculated on the SPC, based on the coordinates, speed and acceleration of the target at the end of the previous situation.

The proposed method can be implemented in a system, the block diagram of which is shown in the drawing. Blocks: 1 - ONS; 2 - SPC.

Links between blocks: 1-2 - calculated trajectory and speed of movement of the SPC to the target; 2-1 - current coordinates and speed of the SPC, current coordinates and speed of the target.
