摘要
自由空间光通信(FSO)是以激光为载波,以大气为传输媒质的新型通信技术,然而传统FSO系统只能实现定点通信,并不具备"动中通"的能力。为了克服传统FSO定点通信的缺点,实现"动中通",本文首先对FSO的移动终端作了初步设计,分析了各部分的功能,然后对FSO天线进行了改进,最后介绍了APT(捕获、瞄准、跟踪)的原理,并给出其工作流程。
Free space optical communication is a new communication technology in which is promulgated through atmosphere and the laser is used as carrier wave.But the traditional FSO just can provide directional communication and can not communicate when it is moving.In order to overcome this disadvantage,the preliminary design of space laser communication system is given and the functions of every part are introduced in this paper firstly.Then the antenna＇s design is improved.The APT（Acquisition,Pointing and Tracking） technology and its process are described finally.
