宽幅SAR监测地表形变研究现状与进展

PRESENT SITUATION AND PROGRESS OF WIDE SWATH SAR FOR MONITORING CRUSTAL DEFORMATION

介绍宽幅SAR的成像处理方法,比较宽幅SAR与传统SAR的成像原理,并对其研究与应用方向如宽幅W SM与IM干涉测量、基于宽幅SAR的大气效应的改正方法、CR技术在宽幅SAR中的应用和PS技术在宽幅SAR中的应用等进行探讨。

The wide swath SAR （ScanSAR model） has some advantage, such as wider swath and short interval, and it can form interferometry with else SAR models for example IM model, so that more interference images can be generated in data processing. Therefore, ScanSAR model can be used in deformation, especially small deformation survey in the future. In this paper, wide swath SAR imaging algorithm is introduced and the interference of different SAR models are expatiated. In the end, development direction about wide swath SAR, for example, interferometry between WSM and IM model, atmosphere correction algorithm based on WSM , application and study of CR and PS technique for WSM, are introduced especially.
