太赫兹空间应用研究与展望

Study and Outlook of Terahertz Space Applications

近年来,我国在空间技术领域取得了举世瞩目的成就,多项技术已经达到国际先进甚至领先水平。要保持我国在空间领域的优势地位,必须加强适用于空间技术及应用的新方法、新手段。太赫兹(THz)技术为空间技术的发展提供了新的途径,因此对THz波空间应用技术进行研究非常必要。文章介绍了THz波的性质及特点,综述了THz技术在雷达、通信、遥感及航天工业等方面的应用,并对THz波在空间应用领域进行了展望,希望能够促进THz技术在该领域的研究及应用技术的进步。

Our country has achieved great progress in space technologies in recent years, with many areas reaching the world advanced even world leading level. New methods and tools for space applications are needed to keep our leading position. The development of tcrahertz （THz） technology provides us a new approach, and therefore, the research on space uses of terahertz wave is of great importance. In this paper, we introduce the properties of THz wave, review the applications of THz in the areas of radar, communication, remote sensing and space industry, and give an outlook of THz wave in space applications. We hope it can accelerate the progress of THz technologies in space areas.
