Abstract

FIELD: military equipment.

SUBSTANCE: method for combined destruction of a group of unmanned aerial vehicles with external distribution of targets involves determination of coordinates at each control station (CS) and transmission thereof, as well as data of own barrelled weapons (BW), to a defensive-offensive system (DOS). On each CS, unmanned aerial vehicles (UAV) are detected, their coordinates are determined and transmitted to the DOS, where the UAV coordinates are updated and selected as targets, the distances to the targets for all CS are determined, the targets are distributed between the CS and their updated coordinates are transmitted to the corresponding CS. Each CS assigns a BW to destroy own targets. At BW determines the angular positions of the barrels and transmits them to its own CS, where coordinates of own targets are predicted. Ambient conditions sensors (ACS) of each CS determine wind speed and direction, air temperature and barometric pressure to be transmitted to appropriate CS. At each CS, determining the aiming points coordinates for the means of destruction (MD) in their BW, MD trajectories are calculated with due allowance for external conditions, BW barrel angular positions are defined for MD hitting the targets and transmitted to BW where the barrels are set to required angular positions. At each CS, commands are generated to launch the MD and transmitted to their BW. Remaining targets are distributed between CS in DOS.

EFFECT: high probability of destroying targets.

Description

The invention relates to military equipment, namely to defensive-offensive systems, and can be used for the effective destruction of groups of unmanned aerial vehicles by groups of weapons consisting of barrel weapons distributed in space, with an external distribution of targets.

The closest to the proposed method is the destruction of unmanned aerial vehicles (RU 2784092), in which the control station (CS) detects unmanned aerial vehicles (UAVs) and determines their current coordinates; determines the characteristics of the detected UAVs and selects them as targets; determines the range to targets in the line of sight of the CS and, if they enter the zone of possible destruction, the CS assigns barrel weapons (BW) to destroy these targets; on the assigned BW, the current angular positions of their barrels are determined; the CS predicts the coordinates of the targets; the CS determines the current coordinates of the aiming points for the weapons (A) within the assigned BW, determines the current angular positions of the barrels of the assigned BW necessary for the BW to hit the aiming points, and transmits them to the assigned BW; on the assigned BW, their barrels are brought to the required current angular positions; the CS generates commands to launch the BW and transmits them to the assigned BW.

However, this method does not provide:

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

- taking into account the influence of external conditions on the flight of the SP;

- protection of moving objects from UAVs;

- simultaneous destruction of several UAVs approaching from the same direction. This reduces the likelihood of target destruction.

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

The proposed method is that:

- at each control point they determine their current coordinates, speed and angular position and transmit them, as well as data from their ground forces, to the defensive-offensive system (ONS);

- at each control station, UAVs are detected and tracked, their current coordinates, speeds and angular positions, as well as characteristic features are determined and transmitted to the ONS;

- in the ONS, they specify the current coordinates, speeds and angular positions, as well as the characteristic features of the detected UAVs, determine their characteristics and select the detected UAVs as targets;

- in the ONS, the ranges to targets in line of sight are determined for all control systems and, in the event that targets enter the zones of possible destruction, these targets are distributed between control systems and their updated coordinates, speeds and angular positions, as well as characteristics, are transmitted to the corresponding control systems;

- at each SU they assign ground forces to destroy their targets;

- at the designated SV they determine the current angular positions of their barrels and transmit them to their SU;

- at each control point they predict the coordinates, speeds and angular positions of their targets;

- the external conditions sensors (ECS) of each control system determine the current wind speed and direction, air temperature and atmospheric pressure and transmit them to their control system;

- at each control system, the current coordinates of the aiming points for the SP as part of the designated ground forces are determined, the trajectories of movement of these SP to their targets are calculated taking into account external conditions, the current angular positions of the barrels of the designated ground forces, necessary for the SP to hit the aiming points, are determined, and they are transmitted to the designated ground forces;

- on the designated SV, their barrels are brought to the required current angular positions;

- at each control center, commands are generated to launch the SP and transmitted to the designated SV;

- in the ONS, as targets are destroyed, the remaining targets in line of sight that have entered the zones of possible destruction are distributed among the control units.

The UAV search and tracking system is similar to the known system (RU 2753498). The UAVs are carriers of the ground forces and can be ground, surface, or airborne. The coordinates, velocities, and angular positions of the UAVs are determined by onboard inertial navigation systems, corrected using the global satellite navigation system. The UAV search and tracking systems are part of the UAV search and tracking system and can be similar to the known systems (RU 2401410). Target distribution between the UAVs is accomplished using the known method (US 8063347).

SVs can be small-caliber automatic cannons and heavy machine guns mounted on gyrostabilized platforms. The angular positions of the SVs and their barrels are determined using appropriate sensors. SVs are assigned depending on the characteristics of the SV and the targets.

The ranges to targets are determined by calculations based on the coordinates of the missile system and targets, and the sizes of the zones of possible target destruction are determined based on the characteristics of the missile system and targets.

The DVUs may be similar to those known (RU 2831866). The SP can be high-explosive fragmentation projectiles for cannons and expanding bullets for machine guns. The most vulnerable points of the targets are chosen as aiming points for the SP, based on their characteristics.

The calculation of the trajectories of the SP movement to the targets and the determination of the required angular positions of the SV barrels are carried out using known methods (cyberleninka.ru/article/n/matematicheskoe-opisanie-traektorii-polyota-puli-vypuschennoy-iz-strelkovogo-oruzhiya; library.kuzstu.ru/dl.php?n=140744&type=nstu:common; www.sinopa.ee/so^o001/bol5pra/bo15pr02/ap11/ap11.htm).

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 - DVU of each SU; 4 - SV of each SU.

Links between blocks: 1-2 - refined coordinates, speeds and angular positions, as well as characteristics of targets in line of sight that have entered the zones of possible destruction; 2-1 - current coordinates, speed and angular position, as well as ground control data of each control system; current coordinates, speeds and angular positions, as well as characteristic features of UAVs detected at each control system; 2-4 - current angular positions of the barrels of the assigned ground control systems, necessary for the ground control systems to hit the aiming points; ground control system launch commands; 3-2 - current wind speed and direction, air temperature and atmospheric pressure for each control system; 4-2 - current angular positions of the barrels of the assigned ground control systems.
