Abstract

FIELD: military equipment.

SUBSTANCE: in a defensive-offensive system (DOS), the coordinates, speeds, and characteristics of targets are determined, a carrier with target-killing means (TDM) is assigned, and the carrier is launched. The carrier and TDM determine their coordinates and speeds and transmit them to the DOS, where the coordinates of the aiming points for the TDM are determined, the trajectories and speeds of the carrier and TDM towards the targets are calculated, and the calculations are transmitted to the carrier and TDM, where the carrier and the separated TDM are aimed at the targets in accordance with the calculations. In the absence of communication with the DOS and targets in direct line of sight, the carrier and detached TDMs continue to guide them to the targets in accordance with the calculations, and if there are targets, the carrier captures and accompanies the targets, adjusts the calculated trajectories and speeds, guides the carrier to the targets in accordance with the adjustments, and transmits the adjusted trajectories and speeds to the TDMs, and the detached TDMs capture and accompany the targets, the calculated trajectories and speeds are adjusted, and the TDMs are aimed at the targets in accordance with the adjustments. When there is a connection with the DOS and the targets are in direct line of sight, the carrier and the separated TDMs capture and track the targets, determine the coordinates and speeds of the targets, and transmit them to the DOS to refine the calculated trajectories and speeds.

EFFECT: this increases the probability of destroying the targets.

Description

The invention relates to military equipment, namely to defensive-offensive systems, and can be used to protect weapons separated from carriers with command guidance to group 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 targets.

The proposed method is that:

- in the defensive-offensive system (ONS), targets are detected and tracked and the current coordinates and speeds of targets, as well as their characteristics, are determined;

- in the ONS, a carrier with detachable means of target destruction (SMT) is assigned and the carrier is launched;

- the carrier and the SPC determine their current coordinates and speeds and transmit them to the ONS;

- in the ONS, the current coordinates of the aiming points for the SPC on the surface of the targets are determined, and the trajectories and speeds of movement of the carrier and SPC to the targets are calculated and transmitted to the carrier and SPC;

- the SPC is separated on the carrier at the beginning of the calculated trajectories;

- on the carrier and separated SPC they are guided to targets along calculated trajectories at calculated speeds;

- on the carrier and separated SPC, in the absence of communication with the ONS and targets in direct line of sight, they continue to guide them to targets along calculated trajectories at calculated speeds;

- on the carrier, in the absence of communication with the ONS and the presence of targets in direct line of sight, they capture

and track targets, adjust calculated trajectories and speeds in accordance with the current coordinates and speeds of targets, guide the carrier to the targets along the adjusted trajectory with the adjusted speed, transmit the adjusted trajectories and speeds to the SPC and separate them from the carrier at the beginning of the adjusted trajectories;

- at separated SPCs, in the absence of communication with the ONS and the presence of targets in direct line of sight, they capture and track targets, adjust the calculated trajectories and speeds in accordance with the current coordinates and speeds of the targets, and guide the SPCs to the targets along the adjusted trajectories with adjusted speeds;

- on the carrier and separate SPC, if there is a connection with the ONS and targets are in direct line of sight, they capture and track targets, determine the current coordinates and speeds of targets and transmit them to the ONS to refine the calculated trajectories and speeds.

The ONS is similar to the known one (RU 2753498). The targets can be underground, underwater, ground, surface, air and space (in the form of military objects, weapons systems, missiles, torpedoes and lasers). The carrier can be underwater, air and space (in the form of a missile and torpedo). The SPC can be underwater, air and space (in the form of missiles, torpedoes and lasers).

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

The coordinates, speeds and characteristic features of targets 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 targets are determined in the ONS by analyzing their characteristic features.

The carrier and SPC are assigned based on their coordinates and characteristics and the coordinates, characteristics and predicted trajectories of the targets. Aiming points are selected in the most vulnerable places of the targets in accordance with their characteristics.

The trajectories and speeds of the carrier and the SPC towards the targets are calculated based on the condition of their 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 colliding with the aiming points at the required angles with the required speeds. The coordinates and dimensions of underwater third-party objects are determined in the hydroacoustic system and transmitted to the ONS.

After separation of the SPC from the carrier, the redistribution of aiming points between them is carried out by correcting their calculated trajectories and speeds.

The higher the speed of the SPC, the higher their inertia and lower their maneuverability. The ratio of speed and maneuverability for the SPC when approaching targets is optimized by setting the speeds necessary and sufficient to destroy the targets upon collision.

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

When communication is restored, guidance of the carrier and the SPC to targets continues with the help of 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 - carrier with detachable SPC; 3 - SPC separated from the carrier.

Links between blocks: 1-2 - calculated trajectories and speeds of movement of the carrier and detachable SPCs to targets; 1-3 - calculated trajectories and speeds of movement of SPCs separated from the carrier to targets; 2-1 - current coordinates and speeds of the carrier and detachable SPCs, current coordinates and speeds of targets; 3-1 - current coordinates and speeds of SPCs separated from the carrier, current coordinates and speeds of targets.
