摘要
从轨道方程出发，对影响卫星光链路接收机带宽的主要因素――多普勒频移进行了研究。在对法拉第反常色散滤光器(FADOF)透射及调谐特性进行理论和实验研究的基础上，提出利用法拉第反常色散滤光器的多峰及可调谐特性的多种新方案来适应不同轨道捕捉点的需要。滤光器带宽典型数据为0.01nm～0.02nm。
Abstract
The Doppler frequency shift, the main factor restricting the bandwidth of receiver in inter satellite laser link, with orbit equations is calculated. On the base of theoretical and experimental study in transmission and tunable characteristic of Faraday anomalous dispersion optical filter (FADOF), several novel schemes are proposed based on FADOF′s multi peak and tunable characteristic, to meet the acquisition requirements in different orbit positions. Typical bandwidth of filter is 0.01 nm～0.02 nm.
