摘要

分析了ScanSAR-Stripmap干涉测量的相位组成

指出其因非同步数据引起的特有相位项

并通过实验验证了该相位项的存在。提出一整套ScanSAR-Stripmap干涉测量方法

借助JPL开发的开源干涉测量软件ROI

AC的相应模块实现干涉处理过程

重点解决了ScanSAR-Stripmap两种模式数据间的配准以及相干性的提高等问题。用EnvisatASAR数据验证了该方法的可行性。最后将实验结果同常规条带式干涉测量结果做了对比与分析

验证了该方法的正确性。

Abstract

This study analyzes the main phase contributions of ScanSAR-Stripmap interferometry and further points out the special component caused by unsynchronized echoes

which is then verified in the experiment. The whole process of ScanSAR-Stripmap interferometry has been proposed and implemented with the help of relating modules of the Repeat Orbit Interferometry Package （ROI

AC） developed by Jet Propulsion Laboratory （JPL）. Coregistration and improvement of coherence are solved emphatically. Finally

ScanSAR-Stripmap interferometry is realized using Envisat ASAR data and the results are compared with those of traditional Stripmap-Stripmap interferometry for validation.
