Abstract

The invention provides a fighter aircraft avoidance maneuvering strategy set generation method in a simulation environment. The method fully considers a plurality of tactical requirements of a fighteraircraft for avoiding an air-to-air missile in a simulated short-distance air combat environment, and redefines and models an avoidance maneuvering decision problem into a multi-objective optimization problem. Through an improved multi-objective evolutionary algorithm, a non-dominated avoidance maneuvering strategy set capable of reflecting different tactical requirements is obtained. The strategy set can enable the fighter aircraft to give consideration to the advantages of safety and confrontation tactics in the avoidance maneuvering process, the selection of avoidance maneuvering strategies under different air combat situations or tactics requirements is met, and the short-distance air combat efficiency of the fighter aircraft in an air combat game and an air combat simulation system can be improved.

Description

technical field [0001] The invention belongs to the technical field of computer simulation and method optimization, and in particular relates to a method for generating a maneuver strategy set for fighter jets to avoid air-to-air missiles in a simulated environment. Background technique [0002] Both air combat confrontation games and air combat simulation systems use computer simulation to simulate the entire combat process of fighter jets in a detailed and realistic way. In order to effectively improve the authenticity of user experience and the ease of control of combat games and simulation systems, it is necessary Angle simulation design combat games and simulation systems, and more importantly, tactical simulation and its convenient interactive design, so as to restore the authenticity of air combat and improve the user's control level in confrontation games and simulation systems. [0003] In air combat confrontation games and air combat simulation systems, fighter jet...
