地球同步卫星(GEO)对地激光通信系统具有通信速率高、保密性好等优势.但系统的光学天线暴露在星体外部,太阳照射对可通率影响严重.针对某GEO对地激光通信系统,不同长度遮光罩对太阳规避造成的可通率及比刚度影响的分析,证明增加遮光罩长度系统可通率提升效果明显.对现有遮光罩形式进行了分析与总结,简述工程中遮光罩长度的确定与限定条件,为优化设计GEO激光通信系统遮光罩及提高系统可通率提供技术基础.

GEO to ground laser communication is characterized by high speed,security. The optical antenna of GEO la-ser communication system exposes outside of satellite. Solar radiation unable to avoid,it affects the optical system seri-ously, reduces available probability. Analyze the effect of these factors for available probability and emphasize analysis the effect of baffle's length. The results show that, increase the length of baffle can increase the available probability. The paper hood length determination and in the engineering qualification.Then in order to optimize the design of baffle GEO laser communication systems summarizes the baffle structure form,provide support for increase the performance of baffle.
