空间光通信ATP系统设计中的基本概念及关键参数探讨

THE ANALYSIS OF SOME MAJOR PARAMETERS IN ATP SYSTEM DESIGN

空间光捕获、跟踪、对准(ATP)技术的采用是为了保证空间光通信系统建立可靠通信链路,它是实现空间光通信需要首先突破和解决的关键技术。空间光通信ATP子系统中的瞄准误差等关键参数直接影响系统总体性能以及对总体设计指标的确定,在一定程度上还决定了空间光通信系统的重量、体积以及系统制作的复杂程度。因此,开展对ATP技术的研究对实现空间光通信有着重要的现实意义。简单介绍ATP系统的典型结构,分析ATP系统瞄准误差的产生、计算以及ATP跟瞄精度对系统整体设计的影响,同时给出对ATP系统的部分仿真结果。

The acquisitiontrackingpointing(ATP) technology is a very important one that should be finished first for optical communication. In this paper, the ordinary ATP system structure and the relationship betwenn pointing deviation and some major system parmeters are described and analyzed. It's helpful for us to recognize free space optic communication deeply and make a perfect design for a ATP system.
