| Abstract: | 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. |

| Keywords: | Terahertz deep space observation blackout space network Terahertz radar |
