Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to self-propelled projectile guidance systems and relates to a method of evading a target hitting facility from interceptors. When implementing the method in a defensive-offensive system (DOS), coordinates, speed and characteristics of a target are determined, a target hitting facility (THF) is assigned and its data is transmitted to a control station (CS), where the THF is launched. On the THF, its coordinates and speed are determined and transmitted through the CS to the DOS, where the trajectory and speed of the THF to the target are calculated and transmitted to the CS, where guidance commands of the THF to the target are generated and transmitted to the THF. In DOS, coordinates, speeds and characteristics of interceptors are determined, their trajectories are predicted and coordinates of places of possible destruction of THF by interception means are determined, as well as coordinates of places of beginning of evasion of THF from interception means. In DOS, at approach of THF to each point of evasion beginning, the path and speed of evasion are calculated and transmitted to CS, where evasion commands are generated and transmitted to THF.

EFFECT: increased probability of target hitting facility evasion from interception means.

Description

The invention relates to guidance systems for self-propelled projectiles, namely to defensive-offensive systems, and can be used to evade means of hitting targets from interception means launched by the enemy.

The closest to the proposed method is the method of missile evasion from interception means (ru.wikipedia.org, Anti-missile maneuver, section Missiles), in which the current coordinates of the target are determined; the missile is launched; its current coordinates are determined on the missile; commands for guiding the missile to the target are generated; missile interception means launched by the enemy are detected and their current coordinates are determined; commands for the missile to evade each interception means and continue moving toward the target are generated.

However, this method does not provide:

- high reliability of detection of interception means, since detection means on the missile are subject to influence from the enemy;

- high accuracy of determining the coordinates of interception means, since it does not provide for their visibility from different directions;

- optimization of the missile's evasion of interception means, since the missile's computing power is limited.

All this reduces the probability of the means of destruction of the target evading the means of interception.

The purpose of the invention is to increase the probability of a means of hitting a target evading interception means.

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;

- the target destruction means (TDM) and the control station (CS) are assigned to the ONS, and the TDM data is transmitted to the CS;

- the SPC is launched at the SU;

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

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

- the control system generates commands for guiding the SPC to the target along the calculated trajectory at the calculated speed and transmits them to the SPC;

- in the ONS, they detect and track the means of intercepting the SPC launched by the enemy, and determine their current coordinates and speeds, as well as characteristics;

- in the ONS, they predict the trajectories of interception means and determine the current coordinates of the locations of possible destruction of the SPC by interception means, as well as the current coordinates of the locations of the beginning of the SPC evasion from interception means;

- in the ONS, when the SPC approaches each place where the evasion begins, the trajectory and speed of the SPC evasion from the corresponding interception means and continuation of movement to the target are calculated and transmitted to the control system;

- at the control center, commands are generated for the SPC to evade each interception vehicle and continue moving toward the target along the calculated trajectory at the calculated speed and transmitted to the SPC.

The ONS is similar to the known one (RU 2753498). The target may be air, underwater, underground, air-underwater, and air-underground (in the form of a military object, weapon system, missile, or torpedo). The SPC may be air, underwater, air-underwater, and air-underground (in the form of a missile or torpedo). The interception means may be air, underwater, and air-underwater (in the form of missiles or torpedoes).

The SPC is assigned based on its efficiency. The coordinates and speed of the SPC are determined in the onboard inertial navigation system, corrected using the global satellite navigation system.

The coordinates, speeds and characteristic features of the target and interception means 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, where the characteristics of the target and interception means are determined by analyzing their characteristic features.

The most vulnerable point of the target is selected as the aiming point for the SPC 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 colliding 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 evading interception means is optimized by setting the speed necessary and sufficient for evasion, and when approaching the target - by setting the speed necessary and sufficient for destroying the target upon collision.

The coordinates of the places where the SPC begins to evade interception means are selected on the SPC trajectory from the condition of providing the SPC with time sufficient for evasion - depending on the places where the SPC can be hit by interception means. The trajectories and velocities of evasion are calculated in a known manner (RU 2794300).

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

Blocks: 1 - ONS; 2 - SU; 3 - SPC.

Links between blocks: 1-2 - TPS data, calculated trajectory and speed of TPS movement to the target, calculated trajectory and speed of TPS evasion from each interceptor and continuation of movement to the target; 2-1 - current coordinates and speed of TPS; 2-3 - commands for TPS guidance to the target along the calculated trajectory with the calculated speed, commands for TPS evasion from each interceptor and continuation of movement to the target; 3-2 - current coordinates and speed of TPS.
