摘要
太赫兹频段在空间研究及应用领域具有独特的优势。太赫兹频段的科学载荷及气象载荷可以为探测空间信息及地球大气信息提供全新的视角;天基太赫兹预警雷达可以为航天器自身安全及弹道目标中段探测提供有力工具;太赫兹波段的通信链路具有带宽大的显著优势,以太赫兹链路为基础的空间网络具有良好的生存能力;太赫兹测控通信链路也是突破高速飞行器黑障问题的有效解决方案。
Terahertz band has many advantages in space researches and applications. Scientific and meteorological pay-loads in THz band provide a new method for space information observation and earth atmosphere observation. Spaceborne THz radar will endue spacecraft with abilities of self-defense early-warning and midcourse targets detection. THz communi-cation links have much wider bandwidth. The space network based on THz links is robust. THz band may realize TT＆C link without blackout interruption.
