摘要
根据实际高轨道对地激光通信技术指标,针对高轨对地激光通信使用Matlab软件建立旋转双光楔式捕获系统的数学模型,并对其进行分辨率分析以及转速分析。结果表明:该方案分辨率为14.824μrad,应用在高轨对地通信所需最大转速为0.26 rad/s,可以满足高轨道卫星平台对地激光通信的指标要求。双光楔捕获方案在高轨对地激光通信方面具有实用研究价值。
According to GEO-to-ground laser communications technology indicators,in this paper,mathematical model of the double- rotating-wedge system is established.lts rotational speed and resolution have been analyzed through software Matlab. The resolution is 14.824rad,and the the maximum required speed is 0.26 rad/s. The results shown that the modle of double--rotating--wedge system meets the requirements of laser communication for GEO--ground link.
