Abstract
Target track is an important research dot in weapon performance testingfiled, to stable track the flying target in optical detection system and testing instrument, horizontal trajectory tracking system based on rotating mirror was researchedin this paper.A horizontal trajectory tracking method was proposed for the tracking problem in the process of the projectile flight, the design of rotating mirror was analyzed and designed;the calculation method of the rotating mirror tracking system were derived, and the influence factors were studied and analyzed, the rotating mirror rotation control algorithm without considering effect of gravity flight targetwasanalyzed and the angular displacement and angular velocity of the rotating mirror were given in the effective tracking range. Through experiment and calculation, the results show that the tracking system can achieve stable tracking of flying target
