Developments of Interferometric Synthetic Aperture Radar About Monitoring Deformation

Now, application of InSAR (interferometric synthetic aperture radar) to deformation monitoring has become a hotspot for monitoring deformation. The basic principles and data processing procedures of InSAR are introduced in this paper, at the same time, main progresses made in InSAR technology and its application to deformation monitoring are summarized. Through actual examples of application and research from home and abroad, the article figures out existing problems and future of application of InSAR.
