碩士 === 國防大學理工學院 === 兵器系統工程碩士班 === 101 === The aiming point guidance law (APG) is new air-to-air guidance law developing to intercept maneuvering target based on target trajectories estimation. However, APG obtains lager lateral acceleration in the missile launching because navigation ration is constant. According to the fuzzy weighting rule, the study refering the parameters of relative motion between the missile and the target inferences adaptive navigation constant by means of improving generate greater lateral acceleration. In addition, Our design uses an extended state observer (ESO) utilizing target informations acquired from the seeker to establish a simple, effective and fast target trajectory estimation algorithm on the missile computer. Finally, we integrate APG, fuzzy weights inference rules and ESO into modified aiming point guidance law (MAPG) and verify integrated effectiveness of the estimator and the guidance law through simulating different scenarios.
