在数据中继卫星系统中，中低轨航天器常采用差模跟踪技术，完成对数据中继卫星的捕获跟踪，建立高速数据中继传输链路。文章根据某任务跟踪接收机实际设计参数，用Matlab／Simulink软件对和差通道相位差对跟踪性能的影响进行了仿真分析。

Spacecraft in LEO often adopt differential mode tracking technology to realize the acquisition and tracking and establish high-speed data relay transmission link in the data relay satellite system. According to the actual design pa- rameter of tracking receiver in an assignment, the impact of sum-differential channel phase difference on the tracking performance is simulated and analyzed with Matlab/Simulink software in this paper.
