摘要
主要研究星载重复轨道干涉测量技术的原理、数据处理以及其在地表形变监测中的应用。采用ENVISAT ASAR影像作为实验数据,围绕D-InSAR数据处理过程中的关键技术这一主线,对其中的干涉复图像对的配准、干涉图的生成、去平地效应、差分、提取地表形变等内容进行了深入的探讨。
This paper mainly studied the principle of the repeat track interferometry technology, data processing, and its application in surface deformation monitoring. Using ENVISAT ASAR images as the experimental data,rounding the key points of the D-InSAR data processing technology, this paper carried out an in-depth discussion of the single look complex image registration, Interferogram generation, the flatearth Impact subtraction, the differential InSAR, the surface deformation extraction.
