卫星通信系统中天线自动跟踪方法研究

Method of Antenna Automatic Tracking of Satellite Communications System

由于卫星的日漂移导致通信信号失锁或者通信质量比较差，这就要求卫星通信天线具有自动跟踪卫星功能，跟踪功能的实现与跟踪信号有直接关系，本文给出了卫星通信系统中天线系统自动跟踪三种方法的原理及使用当中的优缺点。

The excursion per day of the satellite may causes the communication signals unlocked or bad communication. quality, this requires the antenna be able to track the satellite automatically. The performance of the automatic tracking is directly relative to the signal being tracked. This paper introduces the elements of 3 methods of the automatic tracking of antenna system in the satellite communication system, and discusses their advantages and disadvantages respectively.
