摘　　要：针对现有无线电方法空间信息传输能力不足问题,简要分析了空间激光通信的优势,重点介绍了国内外空间激光通信的发展现状与计划,研究了空间激光通信的未来发展趋势。针对卫星小型化、网络化的发展趋势,提出了一种基于逆向调制技术的空间激光通信及组网方法。结合我国空间激光通信发展现状与不足,总结并分析了相关领域的关键技术。Aiming at the shortage of space information transmission capacity of existing radio methods,in this paper the advantages of space laser communication is briefly analyzed,the development status and plan of space laser communication at home and abroad are emphatically introduced,and the future development trend of space laser communication is studied. Aiming at the development trend of satellite miniaturization and networking,a space laser communication and networking method based on retro-reflector modulation technology was proposed.Combined with the development status and insufficient of space laser communication in China,the key technologies in related fields are summarized and analyzed.
