[0068] 1 Air Combat Modeling under the Interference of Accompanying Decoys

[0069] 1.1 Combat Scenarios

[0070] The given air combat process is as follows: the two combatants are the R side and the B side respectively, the R side is a suicide drone, and the B side is a fighter jet and accompanying flying decoy. After the two sides meet in the air, they attack each other. The B-side fighter jets can directly attack the R-side aircraft, and the R-side aircraft need to distinguish combat targets based on the information detected by the sensors, and attack the B-side aircraft by eliminating decoy interference as much as possible. Since it is difficult for today's companion decoys to fully mimic combat aircraft, the companion decoy is not indistinguishable from the R side's airborne sensing devices.

Abstract

The invention discloses an optimal attack threshold value control algorithm for a suicidal unmanned plane under interference of an escort free-flight decoy. The optimal attack threshold value control algorithm is used for analyzing an attack strategy of a hostile suicidal unmanned plane in the presence of the escort free-flight decoy in combination with a Lanchester equation and optimal control. Firstly, based on analysis on battling performance of an onboard sensing device, a differential equation of military strength loss of both battling sides is built so as to obtain the Lanchester equation. Afterwards, the Lanchester equation is taken as a state equation and attack possibility of the unmanned plane is taken as a control variable to respectively obtain optimal control models under a terminal time specified condition and a terminal time variable condition, and the optimal control problem is solved by adopting a gauss pseudospectral method to obtain an optimal attack strategy. At last, influences caused by performance parameters of a sensor to battling results are analyzed, and simulation results prove the reasonability of the models and the effectiveness of the algorithm.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and relates to an optimal attack threshold control algorithm of a suicide unmanned aerial vehicle under the interference of flying decoys. Background technique [0002] With the continuous development of UAV technology, UAVs have gradually been applied to direct combat tasks such as ground attack and anti-radiation attack from the initial target aircraft and auxiliary combat methods such as reconnaissance and detection. And it is foreseeable that in the near future, drones will gradually participate in air combat and become an air strike force that cannot be ignored. However, due to technical reasons, it is difficult for drones to mount missiles for air combat today, and using the drone itself as a weapon to kill enemy aircraft is an alternative. [0003] At the same time, in order to improve the survivability of fighters on the battlefield, the corresponding decoy jamming techn...
