太赫兹雷达技术的发展现状及其关键技术

Progress and Current State of THz Radar and Its Key Technology

太赫兹对远红外和微波技术具有很好的互补性,近年来各国对太赫兹技术进行了研究,特别是太赫兹技术在雷达上的应用研究取得了相应的成果。本文就国内外太赫兹雷达的发展现状进行了阐述,并讨论了该雷达系统所涉及的几个关键技术,进而展望太赫兹雷达的未来发展趋势。

The terahertz radiation(THz) is a great supplement for the infra-red and microwaves technology. Thus, the study of THz has been initiated in many nations and considerable results in radar applications have been achieved. This paper expounded the THz radar’s development of the status quo, and discussed the key technologies of THz radar system. At last we described the future development trend.
