During the development of aircraft, physical test is time-consuming and costly. The appearance of hardware in-the-loop system gives an effective solution to this problem. The hardware in-the-loop system is mostly composed of target motion simulation system, aircraft attitude simulation system, loaded force moment simulation system and the trajectory simulates system. In this system, the performance of entire aircraft can be test and it can save much time and money, so the system is taken more and more seriously by most country. As an external field environment simulator, the target motion simulation system plays a vital role in the hardware in-the-loop system, and it is necessary to carrying out detailed analysis on it. The realizing way, determination of indices and the development of target simulator are the main contents of this paper.In this paper, the program of two-dimensional turntable add target simulator be proposed and demonstrated after compared variety of ways of target simulation. The parameters of the two-dimensional turntable are determined according to the parameters of Seeker. Indicators of the target simulator are demonstrated and determined according to parameters of the two-dimensional turntable and seeker. Visual target simulator is developed by cooperation of optical R & D center and our department. The performance indicators were satisfied with design requirements through analysis. Quasi-static case analysis and modal analysis of the visual target simulator are made on the basic of structural design and finite element modeling. The feasibility of the initial design are verified. Constraints and boundary conditions of target simulator for structural optimization are determined through comprehensive errors analysis of the two-dimensional turntable and the optical target simulator, and then optimal design for a lightweight is excuted.
