| Abstract: | 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. |
