| Summary: | 碩士 === 國防大學中正理工學院 === 兵器系統工程研究所 === 94 === This thesis will establish the simulation environment which can analysis and supply the air combat fighters equipped with air-to-air missile, and find the missile capture area and the fighter evasive range. This thesis is divided into four parts. Firstly, the governing equations of motion and the seven combat strategies of a fighter are introduced. The optimal strategy is determined in accordingly with the theory of zero-sum two-player games. The key characteristic is the suitable scoring functions and the resultant scoring function. The resultant scoring function is used to provide a combined scores and the scoring functions including an orientation score, a relative range score, etc., which can reflect the real situation of air-to-air combat. Second, we introduce pursuit guidance laws and equations of motion of a missile. We apply feedback linearization control method to obtain the accelerations to implement pursuit guidance law. The solution makes warhead direction follow with line-of-sight. The damage scoring function by fragmentation warhead is also defined. Third, we implement three-dimensional pursuit guidance law with feedback linearization control method and study the effects of parameters, e.g. control gain, time delay, etc. Finally, the missile capture areas and the fighter evasive ranges are studied in different air combat cases, e.g., pilot’s intelligence, aircraft performance. With the information of capture areas and evasive ranges, the optimal distance to launch missile and the last chance to escape from missile can be predicted.
