Method and system for multi-UAV cooperative target allocation in confrontation environment

Abstract

This application provides a multi-UAV cooperative target allocation method and system in a confrontation environment, in which, based on the possible occupancy strategies and target allocation strategies of the opposing parties, the target for each UAV of one's own side is determined, and a zero-sum matrix is ​​established. The game model solves the multi-UAV cooperative target allocation problem in the confrontation environment by solving the mixed strategy Nash equilibrium solution of the model. Furthermore, when solving the zero-sum matrix game model, establish the game matrix of the scalable game and solve it to obtain the current mixed strategy Nash equilibrium, and then use the method of variable occupancy iterative search to solve the game. Solve the third game strategy and the fourth game strategy, and use the iterative method to determine the game matrix of the scalable game that is used to determine the most advantageous game strategy for a certain party in the confrontation to be solved, and solve the game of the determined scalable game The matrix can effectively reduce the calculation amount and improve the calculation efficiency.

Description

technical field [0001] The invention relates to the field of security, in particular to a multi-UAV cooperative target allocation method and system in a confrontational environment. Background technique [0002] UAVs can autonomously complete given tasks in a variety of environments, effectively reducing labor costs. Compared with manned aircraft, UAV has the characteristics of no casualties, strong maneuverability, lighter weight, and lower cost. It has become one of the important members of modern air combat weapons and equipment. Due to the limited number and performance of weapons and sensors carried by a single UAV, its ability to perform air combat tasks is limited accordingly, and effective coordination of multiple UAVs can better complete air combat tasks. The decision-making technology of line-of-sight coordinated air combat has received more and more attention. [0003] For the multi-UAV over-the-horizon cooperative air combat decision-making problem, most of the...
