Abstract

FIELD: missile guidance systems.

SUBSTANCE: in a hydroacoustic system, the coordinates and speeds of targets and interception means (IM) are determined underwater and transmitted to a defensive-offensive system (DOS), where the coordinates and speeds of targets and IM are determined, an air-underwater carrier missile (CM) with air-underwater missiles is assigned, and the CM data is transmitted to a control station (CS), where the CM is launched. The coordinates and speeds of the CM and missiles are determined and transmitted through the CS to the DOS, where the coordinates of the aiming points on the surface or underwater surface of the targets are determined, the trajectories and speeds of the CM and missiles towards the targets are calculated, and the information is transmitted to the CS, where commands are formed to separate the missiles from the CM and transmit them to the CM, as well as commands to aim the CM and missiles at targets and transmit them to the CM and missiles. The DOS predicts the trajectories of the IM and determines the coordinates of the places of possible damage to the CM and missiles and the places where they begin to evade the IM, when the CM and missiles approach them, they calculate the trajectories and speeds of their evasion and transmit them to the CS, where evasion commands are formed and transmitted to the CM and missiles.

EFFECT: it increases the probability of destroying surface targets with missiles.

Description

The invention relates to missile guidance systems, namely to defensive-offensive systems, and can be used to destroy group surface targets with groups of air-underwater missiles separated from air-underwater launch vehicles, while evading interception means launched by the enemy.

The closest to the proposed method is the destruction of surface targets by missiles separating from the launch vehicle (RU 2022128083), in which the defensive-offensive system (ONS) detects and tracks surface targets above water and determines the current coordinates and velocities of the targets, as well as their characteristics; the ONS assigns an air-underwater launch vehicle (LV) with air-underwater missiles, as well as a control station (CS), and transmits LV data to the CS; the CS launches the LV; the LV and missiles determine their current coordinates and velocities and transmit them through the CS to the ONS; the ONS determines the current coordinates of the aiming points for missiles on the surface or underwater surface of targets, as well as calculates the air-underwater trajectories and velocities of the LV and missiles to the targets and transmits them to the CS; the CS generates commands to separate the 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 does not provide protection for the launch vehicle and separated missiles from interception, which reduces the likelihood of destroying targets.

The purpose of the invention is to increase the probability of destroying surface targets with missiles.

The proposed method is that:

- in the hydroacoustic system, surface targets are detected and tracked underwater, the current coordinates and speeds of targets, as well as their characteristic features, are determined, and they are transmitted to the ONS;

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

- in the ONS, an air-underwater launch vehicle with air-underwater missiles, as well as a control system, is assigned, and the launch vehicle data is transmitted to the control system;

- the launch vehicle is launched at the SU;

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

- in the ONS, the current coordinates of the aiming points for missiles on the surface or underwater surface of targets are determined, and also the air-underwater trajectories and speeds of movement of the launch vehicles and missiles to the targets are calculated and transmitted 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;

- in the hydroacoustic system, they detect and track the means of intercepting launch vehicles and separated missiles (SPR) under water, determine their current coordinates and speeds, as well as characteristic features, and transmit them to the ONS;

- in the ONS they detect and track the SPR over water and determine their current coordinates and speeds, as well as characteristics;

- in the ONS they predict the trajectories of the SPR and determine the current coordinates of the locations of possible destruction of the LV and separated missiles and the locations where they begin to evade the SPR;

- in the ONS, when the launch vehicle and separated missiles approach each place where the evasion begins, the air-underwater trajectories and evasion speeds of the launch vehicle and separated missiles from the SPR and the continuation of movement towards the targets are calculated and transmitted to the control system;

- the control system generates commands for the launch vehicle and separated missiles to evade the launch vehicle and continue moving toward targets along calculated trajectories at calculated speeds and transmits them to the launch vehicle and separated missiles.

The ONS is similar to the known one (RU 2753498). The hydroacoustic system is similar to the known one (iz.ru/news/647107). The launch vehicle and missiles are similar to the known one (naked-science.ru/community/498555). The SPR can be air, underwater and air-underwater (in the form of missiles and torpedoes).

Launch vehicles, missiles and control systems are assigned based on their effectiveness. The coordinates and speeds of launch vehicles and missiles are determined in onboard inertial navigation systems, corrected using the global satellite navigation system.

The coordinates, speeds and characteristic features of targets and SPR above water are determined at search and tracking stations as part of the ONS, and under water - at search and tracking stations as part of the hydroacoustic system. The characteristics of targets and SPR are determined in the ONS by analyzing their characteristic features.

The most vulnerable points of the targets are selected as aiming points for missiles in accordance with their characteristics. The trajectories and speeds of the LV and missiles moving towards the targets are calculated based on the condition of their bypassing third-party objects and the collision of missiles with aiming points at the required angles with the required speeds. The coordinates and sizes of underwater third-party objects are determined in the hydroacoustic system and transmitted to the ONS.

After the missiles are separated from the launch vehicle, the redistribution of targets between them is carried out by correcting their calculated trajectories and speeds.

The higher the speed of the launch vehicle and missiles, the higher their inertia and lower their maneuverability. The ratio of speed and maneuverability for the launch vehicle and missiles when evading the SPR is optimized by setting the speeds necessary and sufficient for evasion, and when the missiles approach the targets - by setting the speeds necessary and sufficient for destroying the targets upon collision.

The starting points for evasion of the launch vehicle and missiles from the SPR are selected on their trajectories depending on the locations of possible destruction of the launch vehicle and missiles - from the condition of providing the launch vehicle and missiles with sufficient time for evasion. The trajectories and velocities of evasion are calculated in a known manner (RU 2794300).

Communication between the control system and the launch vehicle and the missiles on the underwater part of their trajectories is carried out in a known manner (RU 2730749). The transitions of the launch vehicle and missiles from one medium to another increase the probability of their evasion from the SPR.

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