空间激光通信组网技术与应用研究进展
Research progress of space laser communication networking technology
摘要
Abstract
Laser communication utilizes light waves as the transmission medium.It offers many advantages,including high data rates,expansive bandwidth,compactness,robust interference resistance,and superior confidentiality.It has the critical capability to enable high-speed transmission and secure operation of space information networks.Prominent research institutions have committed to studying a series of challenges that need to be solved in the process of networking laser communication technology,including point-to-multi-point simultaneous laser communication,all-optical switching and forwarding of multi-channel signals with-in nodes,node dynamic random access,and network topology design.Numerous demonstration and verifica-tion experiments have been conducted,with a subset of these research results finding practical applications.Based on the analysis and discussion of space laser communication networking technology,this paper sum-marizes the development of laser communication networking technology both domestically and internation-ally,focusing on the application of laser communication networking technology in the fields of satellite con-stellations,satellite relays,and aviation networks.Furthermore,it presents a review of pertinent domestic re-search methodologies,experimental validations,and technical solutions.Finally,it predicts the development trend of laser communication networking technology and applications.关键词
