分析了跟踪角速度、功率、跟踪精度等因素对大气激光通信系统中瞄准、捕获和跟踪子系统参数选择的影响 ,给出了波束发散角、扫描角范围、接收视场等主要参数的选择原则 ,对地面终端光通信系统设计背景提出了瞄准、捕获和跟踪子系统的相应指标。
The effects of tracking angular velocity, power and tracking accuracy on the selection of aiming, trapping and tracking subsystems in atmospheric laser communication system are analyzed. The selection principles of the main parameters such as beam divergence angle, scanning angle range and receiving field are given. Aiming at the design background of the terrestrial terminal optical communication system, the corresponding indexes of aiming, capturing and tracking subsystems are proposed.
