摘要
卫星合成孔径雷达干涉技术((InSAR)通过对地面同一地区两次或多次平行观测成像得到的复图象对进行处理可获得数字地面模型,用以监测地表面变化。本文简单叙述了(InSAR)基本原理、处理流程及方法,并通过天津SAR数据的处理,详细介绍了SAR数据处理整个过程,之后给出了基于ERS-2天津地区原始数据的实验结果形成的干涉图及数字高程图。
The Interferometric Synthetic Aperture Radar(InSAR) uses the phase difference of the radar returns in two or more complex SAR images,acquired at separate times from a nearly exactly repeating orbit,to get a DEM to monitor surface deformation.The paper mainly introduces the basic theory,procedure and method of InSAR data processing.As an example,the interferometric map and DEM map of Tianjing stem from Tiangjing SAR data processing based on ERS-2 are presented.
