摘　　要：太赫兹频段是宏观电子学向微观光子学过渡的纽带,是电磁频谱中最近被开发的频段,在遥感领域受到了特别关注。介绍了太赫兹频段的技术优势,以及在天文观测、地球气象观测、目标参数测量、反隐身雷达及探测雷达等领域的发展状况及设想,探讨了太赫兹雷达在弹道目标探测及空间来袭目标告警等场景下的应用。揭示了太赫兹技术在遥感领域良好的应用前景。Terahertz band is the bridge connecting the electrical waves and light waves in electromagnetic spectrum. It is the latest developed band,and attracts much attention in remote sensing field. The advantages of Terahertz wave are analyzed in astronomical observation , metrological observation , target Radar Cross-Section（RCS） measurement , counter-stealth , and detecting radar applications,and their development trends are discussed and envisioned as well. The application of Terahertz radar in the scenes of ballistic target detection and space target alarm are discussed in detail. A good prospect is suggested for the application of Terahertz techniques in remote sensing fields.
