摘要
空间激光通信凭借其带宽优势, 成为未来高速空间通信不可或缺的有效手段, 是近年来国际上的研究热点。本文详细介绍了美国、欧洲和日本在空间激光通信技术领域的最新研究进展和未来发展规划, 总结了国内外空间激光通信演示计划的主要参数指标。通过对空间激光通信最新研究计划的分析, 归纳出空间激光通信高速化、深空化、集成化、网络化、一体化5个发展趋势, 以及需要突破的高阶调制、高灵敏度探测、多制式兼容、“一对多”通信等关键技术。为我国激光通信设备及相关研究提供借鉴和参考。
Abstract
Free-space laser communication, by virtue of its bandwidth advantage, has become an indispensable and effective means for high-speed space communication in the future, and is a research hotspot in recent years. This paper gives a detailed introduction in the latest research progress and future development planning of free-space laser communication technology in the United States, Europe and Japan, and summarizes the main parameters of the free-space laser communication demonstration program at home and abroad. Through deep analysis of the latest research plan of free-space laser communication, we summarize five future development trends of free-space laser communication, namely high-speed, deep-space, multifunction, networking, and integration, as well as key technologies that are expected to break through, such as high-order modulation, high-sensitivity detection, multi-system compatibility and “one-to-many” communication. These technologies provide guidance and reference for free-laser communication equipment and related research in China.
