Key Technology Research On Multi-aircraft Cooperative And Multi-target Attack

This thesis mainly works on multi-aircraft cooperative multi-target attack intelligent fire control system and super-maneuver attack system. It is supported by the Tenth Five Years Early Research Foundation of China Air Force.Effective guidance is one of the most important tasks to the performance of air-to-air missile. Based on the proportional navigation, Fuzzy logic and genetic algorithm are combined to develop an evolutionary fuzzy guidance 1 aw with s elf-adapt region for the air-to-air missile guidance. Then we simulated the result of air-to-air missile attack using MATLAB.The decision problem in cooperative air combat is an important content of multi-aircraft cooperative multi-target attack. The mathematical model of tactic decision algorithm in multi-aircraft cooperative air combat is built, and the mathematical model of self-priority and cooperative priority are also presented. And we used BP network to targets assign in cooperative air combat, SOFM network is used to the attacking sequence decision problem in cooperative air combat.Nonlinear dynamic inversion control law can better solved the control problem of super-maneuver flight. Consider the engineering implement and the idiographic request of Air Force Equipment Department, this thesis used C++ programming language to describe dynamic inversion control law and model of the fourth generation fighter. For the convenience of user interface and maintenance, we encapsulated the software as a DLL.This thesis also do a research on air-to-ground attack. We used cooperative priority method to do the attack decision of single fighter to multi ground targets. Then we analyzed the change process of trajectory in air-to-ground missile attack, built the movement equations based on the center of gravity of every segment. In the end we gave the whole trajectory simulation result of air-to-ground attack.This thesis expounded the modeling technology of 3D objects in computer animation simulation and the method of using OpenGL engine in Visual C++ environment, recommended correlative programming technology of the platform. Perfected the 3D animation simulation of super-maneuver wrestling in modern air combat using OpenGL, simulated multiplicate maneuver actions in air combat.
