在卫星光通信的链路建立过程中，粗瞄误差不对称度较高时，同样的扫描时间限制内分行扫描可以获得更高的捕获概率。

Giving the same limit for the acquisition time, a larger acquisition probability is obtained with the raster scanning during the link foundation when the coarse pointing errors asymmetry is high.

采用信标光是完成卫星激光通信捕获过程的一种重要手段，信标光的远场分布对捕捉概率和捕获时间有较大的影响。

Using a beacon in the free space laser communication system is an important method of finishing the acquisition course.
