To support the planning of satellite orbit tracking and imaging experiment, and provide effective data for in-orbit test planning,the semi-physical simulation model of ground target tracking is established to simulate the target tracking process. First, this paper analyzes the typical work process of space target tracking system, established the spatial coordinates model of the space target LOS and satellite rendezvous process. Secondly, the mapping relationship between space target motion and tracking system is studied based on the principle of space radial motion principle. The semi-physical simulation’s design principle and the system design scheme of space tracking are given by establishing the radial motion model of the target motion and tracking system. Finally,based on the analysis of the typical space target motion and the design of the semi physical simulation system, the simulation of the space target tracking process with the intersection distance of 60km and the moving speed of 4.2km/s is carried out. The simulation results show that This system can realize continuous tracking of space targets,when the system is stable, the miss distance is less than 0.5 pixels, Azimuth tracking velocity stability is 0.0174°/s, the pitch tracking velocity stability is 0.0161°/s. The test shows that the design principle of the simulation system is correct, and the closed-loop control process can be simulated effectively. This test can provide effective data supports for program analysis and control methods on orbit test, real-time monitoring, analysis and test of synchronous control countermeasures of fault verification.
