摘　　要：卫星遥感器种类及数量的增加使卫星信道需要传输的码速率越来越高,如何在有限带宽内将大容量数据实时传回地面站,一直是研究的热点问题。在相同信道带宽条件下,双极化传输技术能将传输码速率提高1倍。文章从双极化传输基本概念入手,重点分析了X波段卫星传输系统中影响双极化传输的关键因素以及克服这些影响的方法,给出的仿真及测试结果可以为相关研究提供参考。The increase of remote sensor＆#39;s variety and quantity results in higher data transmission rate through satellite channel. It＆#39;s an investigation hotspot how to transmit these real-time data to the ground station in the limited band. Polariza-tion multiplexing can double the data rate in the same transmission band. Based on the basic conception of polarization multi-plexing,the key factors affecting the transmission quality are analyzed,as while as methods overcoming such factors. The sim-ulation and test data can provide a useful reference for relevant researches.
