摘要
首先分析了太阳环境对深空激光通信的影响,利用Kerr度规计算出通信激光经过太阳表面时受到太阳引力场影响的通信光偏折角为1.75″-0.12″×10-5。对地球到火星激光通信的环境因素进行了分析,通过Matlab软件仿真得到不同位置(不同激光传输时间)与激光通信发射角度的补偿关系。
First ,we analyze the effects of solar system on deep‐space laser communication ,and obtain that the light deflection angle caused by sun gravitational field is 1 .75″ -0 .12″× 10^-5 by using Kerrmetric .Then the environment influences between Earth and Mars to laser communication are studied . MATLAB‐based simulation calculates the compensation relationship between the positions （at different transfer time） and the laser emitting angles .
