摘　　要：随着空间激光通信技术的发展以及建立抗干扰高速天空地一体化信息网络的需要,研究空间激光通信组网技术迫在眉睫.在分析空间激光通信组网技术难点的基础上,提出了一种新的激光通信组网方案.利用广角扩束镜与双光楔组结合作为多点激光通信系统的光学天线,广角扩束镜可实现对不同方位目标信号光的收集,双光楔组可实现对不同方位目标的同时动态跟踪.以此光学天线为基础,研究了可实现一对多同时空间激光通信的总体方案,设计了系统中的光学天线、中继光学分系统、收发分光分系统等.该方案可为空间激光通信组网提供一种新的技术途径.With the development of free space laser communication technology and the demand of anti-jamming,high-speed integrated information network,the research of high-rate laser communication networking technology is urgent.Based on the analysis of the technical difficulty in space laser communication networking,a new laser communication networking solution is proposed.Wide-angle beam expanders and double optical wedge groups are incorporated as antenna for the multi-point optical laser communication system.The wide-angle beam expander can collect the target signal lights in different directions,and the double optical wedge group can dynamically track different targets simultaneously.The overall scheme of multipoint free space laser communications based on this optical antenna is studied.The optical antenna,relay optical subsystem,transceiver subsystem and so on are designed.The scheme provides a new technical pathway for space laser communication network.
