摘要
Ka频段自动角跟踪系统是中继终端的关键部分,它的捕获和跟踪性能直接影响星间链路质量。阐述了中继终端自动角跟踪系统的组成及其工作原理,并利用Matlab/Simulink软件重点对系统中的跟踪接收机、单通道调制器和天线进行了建模与仿真。仿真结果与理论结果一致,这个仿真模型可以作为跟踪接收机合理的仿真平台。
The automatic angle tracking system working in Ka-band is a key part of the relay terminal. The capture and tracking performance of the system directly affect the quality of inter-satellite link. The composition and principle of the system are elaborated. The modeling and simulation of the tracking receiver, single-channel modulator and antenna in the system are implemented by Matlab/Simulink software. The result of simulation is in accord with that of the theory. The simulation model may serve as a reasonable simulation platform of tacking receivers.
