摘 要:
合成孔径雷达干涉测量(InSAR)技术是近二十年来迅速发展起来的空间对地观测新技术。简述InSAR干涉处理过程的基础上,重点介绍并分析了其关键技术SAR图像配准和相位解缠的常用算法,并对由ERS1/2得到的两幅复杂SAR图像为实验对象,综合使用图像配准和相位解缠的经典算法对SAR图像配准生成干涉图,对干涉图相位解缠。最后简要介绍国内外InSAR技术发展方面的现状及发展趋势。[著者文摘]

Abstract:
As a new technology for observation of earth from space, InSAR has been developed rapidly in last two decades. This paper presents and analyses the main algorithm about the key technologies including the SAR image registration and phase unwrapping algorithms, some related experiment results produced using the classical image registration and phase unwrapping algorithm on two complex SAR images from ERS1/2. Finally, the present status and development of InSAR technology are summarized.[著者文摘]
