摘　　要：大气信道是制约无线激光通信链路性能提高的一个重要约束条件。为了提升通信系统性能,使其能适应远距离、高速率、低误码率的传输需求,在进行系统级设计时根据大气信道激光传输特性进行总体设计与分析是十分必要的。首先对大气激光传输特性展开研究,在实验的基础上对大气湍流、大气衰减效应进行了分析;然后从大气信道约束的角度出发,分析了大气信道中光端机的光学发射天线、光学接收天线、通信系统、瞄准跟踪等子系统的设计方法以及相应的设计参数和优化方法;最后给出了一套大气信道无线激光通信系统的总体设计实例。Atmospheric channel is an important constraint conditions to promote the performance of wireless laser corn-munication link. In order to improve the performance of the system, the demand of long distance transmission, high rate, low error rate that can be adapted. Total analysis based on charmel characteristics, before designing the concrete proposal, is necessary. Firstly, in this paper, the research of character of Atmospheric transmission of laser is focused on and carried on. On the base of experiments, the atmospheric turbulence, atmospheric attenuation so and on, were analyzed. Then, from the view of atmospheric channel constraints, the design parameters and optimization method of the key subsystem are analyzed, such as optical transmitting antenna, optical receiving antenna, communication system,APT （Acquisition, Pointing, tracking）. Finally, an overall design example of atmospheric laser communication system in in atmosphere channel is given.
