Research And Simulation On Air-battle Data Link And Fire Control Of Fighters

Base on air-battle data link of fighters, this thesis research on fire control system and simulation, mainly including the key technology of fighter data link, the super-maneuver flight control system design, the fire control of missile attack, and the 3D visualization simulation of air-battle. Data link is very useful in war, and which is called "fight multiplier". This thesis bring forward the network and data structure of data link, and research on information processing, including the conversion and error compensation of target information, and research on the air-battle decision which base on data link. Nonlinear dynamic inversion control law can better solve the problem of super-maneuver flight control, by which the thesis simulate cobra maneuver and herbst maneuver, and research on system robustness. Consider the engineering implement and the idiographic request of Air Force Equipment Department, we use C++ to describe dynamic inversion control law and model of the fourth generation fighter and encapsulated the software as a DLL. Effective guidance is one of the most important factors to the performance of air-to-air missile. Based on optimal control theory, this thesis give variable coefficient proportional guidance law, and simulate on air-to-air missile and air-to-surface missile by using MATLAB. On Windows platform, this thesis use VC and OpenGL to develop 3D-visualization artificial platform, which can do 3D simulation on airbattle, cobra maneuver and herbest maneuver with better reality and interactivity.
