摘要
太赫兹频段介于红外光波与毫米波之间,是电磁波谱中的重要频段。太赫兹技术已在空间领域展示出良好的应用前景。通过空间太赫兹频段观测可以获得丰富的气象信息、大气信息和深空科学信息。基于太赫兹链路的高频段通信有望突破等离子体黑障的限制,实现无中断的测控通信;高速率小型化的太赫兹通信终端是实现卫星网络的理想选择。太赫兹雷达在航天器自身防御及空间弹道目标预警领域将显示出独特的优势与价值。
Terahertz band is located between infrared and millimeter wave in the electromagnetic spectrum, which shows a good application prospect in space science and technology. Meteorological, atmospheric and deep space information can be obtained by space borne terahertz observation. It is expected to realize TT＆C without radio blackout interruption with terahertz link. Terahertz band is also the optimal choice for realizing space network. Space borne radar systems in terahertz band are useful in self-defense early-warning and midcourse ballistic targets tracking and surveillance.
