摘要
随着信息共享范围和带宽的不断提升,天基宽带通信系统引起了科研界和工业界越来越广泛的关注。本文首先介绍了美军天基通用数据链的发展,并从工作频段和波形体制两个方面对可用的技术和工作体制进行分析和对比,在此基础上对天基宽带通信系统中的若干关键技术进行分析研究。
With the increasing demands of coverage and bandwidth of information sharing,satellite wideband communication systems have attracted more and more attention in both research and industry. This paper firstly introduces the development of space common data link（ space CDL） in U. S.,and then analyzes and compares different choices considering spectrum and waveform design. Finally,some key technologies of satellite wideband communication systems have been discussed and analyzed.
