摘要
InSAR(合成孔径雷达干涉测量)是20世纪后期发展起来的一种新的测量方法,由于其具有能够实现全天时、全天候的对地观测等特点,现已成为空间对地观测技术的研究热点。文中阐述了InSAR中采用人工角反射器的作用,并从几何上推导了InSAR中人工角反射器的原理,并介绍了其制作以及在安装过程中应注意的一些问题,最后对人工角反射器技术在国内外的应用以及存在的问题作了描述。
InSAR （Interferometric Synthetic Aperture Radar）is a new measurement method on later stage of the 20th century. It becomes hot topic of the technical that observe ground from space,because it＇s day- and-night and all-weather imaging capability. This paper points out that why we adopt CR in InSAR and derives the principle of the CR. Some questions on CR facture and installation are introduced. At last, this paper describes the developed of the CR both at home and abroad and the existing problems.
