摘要
随着高分辨率观测技术的发展和高数据率信息传输的迫切需求,研究高速率激光通信的组网技术迫在眉睫。分析了空间激光通信链路组网所需要满足的基本要求及其实现中必须解决的技术难点,提出了组网光学原理,同时研究了一种可用于多目标间同时进行激光通信的技术方案,设计了以旋转抛物面为基底的多反射镜拼接结构的光学天线、中继光学系统以及发射接收与捕获、跟踪和对准(APT)系统,为空间激光通信链路组网提供了新的技术途径。
With urgent demand of the high-resolution observation technology development and the high data rate transmission of information, the research of high-rate laser communication networking technology is imminent. Basic requirement and technical difficulties on the space laser communication networking in realization are analyzed. The new networking optical principle is proposed. A technological solution is studied, which can be used for laser communication through multiple targets at the same time, and an optical antenna of multi-mirror combination is designed based on the paraboloid of revolution, relay optical system, receiving and transmission system and acquisition, pointing, tracking （APT） system. It provides a new technical way for space laser communication network.
