Embodiment Construction
[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the present invention includes but is not limited to the following embodiments.
[0039] The technical scheme adopted by the present invention to solve its technical problem comprises the steps as follows:
[0040] Step 1: Build the three-dimensional motion and constraint models of fighter jets and short-range air-to-air missiles (hereinafter referred to as "missiles") in short-range air combat, and design to avoid termination constraints, including:
[0041] 1) Establish the motion model of the fighter as x f (t 0 )=x f0 ; where the state vector is x f =[x f ,y f ,z f ,v f ,θ f ,φ f ] T , where x f ,y f ,z f is the position coordinate of the fighter in the geographic coordinate system (North-Sky-East), v f is the fighter speed, θ f and φ f are the track inclination angle and track declination angle of the fighter jet, respectively; x ...

The present invention provides a method for generating a fighter evasion maneuver strategy set in a simulated environment, which fully considers multiple tactical requirements of fighter jets for evading air-to-air missiles in a simulated close-range air combat environment, and redefines and models the evasive maneuver decision problem as Multi-objective optimization problem. Through an improved multi-objective evolutionary algorithm, a non-dominated evasive maneuver strategy set that can reflect different tactical requirements is obtained. The strategy set can make the fighter take into account its own security and adversarial tactical advantages in the process of evasive maneuvering, and satisfy the selection of evasive maneuvering strategies under different air combat situations or tactical requirements, thereby improving the fighter's performance in air combat confrontation games and air combat simulation systems. close-range air combat effectiveness.
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] Air combat confrontation games and air combat simulation systems use computer simulation methods to perform detailed and realistic simulations of the entire combat process of fighter jets. The angle simulation design confronts the game and the simulation system, and more importantly, the tactical simulation and its convenient interaction design, so as to restore the authenticity of the air combat, and at the same time improve the user's control level in the confrontation game and the simulation system. [0003] In air combat confrontation games and air combat simulation systems, fighter jets often face the threat of enemy air-to-air missiles. Designing reasonable and effective evasi...
