碩士 === 國防大學理工學院 === 兵器系統工程碩士班 === 101 === Due to the acceleration of gravity, ballistic missiles return to the atmosphere have the characteristics of high-speed. A new type of ballistic missiles have better equipped to change the flight path of mobility in reentry. Accordingly, in the face of the goal to have a high-speed and mobility conditions, general surface to air missiles facing serious challenges in the design of guidance law. In this study, based on the trajectory estimation, the framework of ballistic missile intercept point guidance law is designed to create high-precision and low energy consumption. Target trajectory estimator is based on the lateral acceleration and the interference input estimator of the target trajectory estimator, that can estimate the target trajectory accurately. In addition, the trajectory intercept point guidance law system is based on the trajectory prediction algorithm to establish the guidance law. The approach speed and related parameters as the guidance law are utilized to improve the traditional type of proportional guide. Finally, the fuzzy theory algorithm is introduced to enhance the guidance performance. Expectations through the above method to establish the ballistic missile appropriate and feasible guidance law algorithm.
