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 0 1nm～ 0 0 2nm。
Starting from the orbit equation, the main factors affecting the bandwidth of satellite optical link receiver --- Doppler shift were studied. Based on the theoretical and experimental research on the transmission and tuning characteristics of FADOF, we propose a variety of new schemes that utilize the multimodal and tunable characteristics of Faraday anomalous dispersion filters to adapt to different orbit catching points Need. Typical filter bandwidth data is 0 0 1nm ~ 0 0 2nm.
