| 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. |
