Abstract

FIELD: military equipment.

SUBSTANCE: in a defensive-offensive system (DOS), the coordinates, speed, and characteristics of the target are determined, and a target destruction means (TDM) is assigned and launched. The coordinates and speed of the TDM are determined and transmitted to the DOS, where the coordinates of the aiming point for the TDM are determined, the trajectory and speed of the TDM's movement towards the target are calculated, and the TDM is aimed at the target in accordance with the calculations. In the absence of communication with the DOS and the target in direct line of sight, the TDM continues to aim at the target in accordance with the calculations, and if the target is present, it captures and accompanies the target, adjusts the calculated trajectory and speed, and aims the TDM at the target in accordance with the adjustment. In the presence of communication with the TDM and the target in direct line of sight, the DOS captures and accompanies the target, determines the coordinates and speed of the target, and transmits them to the DOS to refine the calculated trajectory and speed.

EFFECT: this increases the probability of destroying the target.

Description

The invention relates to military equipment, namely to defensive-offensive systems, and can be used to protect weapons with command guidance on targets from enemy radio countermeasures.

There are known methods of radio countermeasures (RU 2755603, RU 2809997) in which the control and navigation channels of weapons with command guidance are suppressed, which reduces the probability of destroying targets. At the same time, methods of protecting such weapons from radio countermeasures are unknown.

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

The proposed method is that:

- in the defensive-offensive system (ONS), they detect and track the target and determine the current coordinates and speed of the target, as well as its 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, in the absence of communication with the ONS and the target in direct line of sight, the SPC continues to be guided to the target along the calculated trajectory at the calculated 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, adjust the calculated trajectory and speed in accordance with the current coordinates

and the target speed and direct the SPC to the target along the adjusted trajectory with the adjusted 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 the current coordinates and speed of the target and transmit them to the ONS to refine the calculated trajectory and 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, if possible, the zones of action of the enemy's anti-missile or anti-torpedo defense, as well as based on the condition of the SPC collision with the aiming point at the required angle with the required speed. The coordinates and dimensions 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.

In the absence of communication with the ONS (as a result of enemy radio counteraction), the SPC is guided to the target using onboard television or hydroacoustic guidance systems. The presence or absence of a target in the direct line of sight of the SPC is determined based on their coordinates and a terrain map.

When communication is restored, the SPC continues to be guided to the target using the ONS.

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.
