空-地激光通信链路波长选择因素分析

The Analysis of Wavelength Selection for Space-to-Ground Laser Communication

空 -地激光通信链路波长选择主要和通信传输所使用的大气随机信道、光束跟踪、捕获、瞄准 (Acquisition,Pointing and Tracking— APT)子系统 ,通信子系统及接收、发射系统采用的主要光电器件等因素有关。本文对影响空 -地激光通信链路波长选择的因素进行了分析 ,并根据上述影响因素开展了对通信波长的研究 ,促进了空 -地激光通信系统的总体设计工作。

In this paper, it is discussed that how to selecte wavelength for space-to-ground laser communication.The condition factors which effect space-to-ground optical communication system,such as atmospheric channel, communication link,APT link,laser power,detector, etc.are analyzed.All this can help us to understand space-to-ground laser communications deeply and make a system design perfect.
