摘　　要：分析了"动中通"中的关键技术天线稳定与波束跟踪,并讨论了它们的不同实现方法。给出了一种把天线稳定和波束跟踪相结合的方法,并把几种实现方式分别在Simulink中进行了仿真,仿真结果表明该方法不仅具有有效性,而且对于误差的修正时间也比较短。The critical technologies of antenna stabilizing and beam tracking in mobile satellite communication are analyzed, and their different implementation methods are discussed. An implementing method is presented which combines the antenna stabilizing with beam tracking. Simulations were made for each of the implementation methods by using Simulink of Matlab. The experimental results showed that the method put forward here was effective and had shorter error correcting time.
