摘要
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.
Abstract
The influence of the factors such as tracking angular velocity, power and tracking precision on the determination of parameters of pointing, acquisition, tracking(PAT) subsystem for atmosphere optical communication is analyzed. The principles of how to determine the important parameters such as angle of beam divergence, scanning area and receiving field of view are also provided. The corresponding specifications of a PAT subsystem of optical communication system in a certain background of ground terminal are obtained.
