A Method of Topographic Change Detection Base InSAR Terrain Matching Technology

This paper studies the situation of the lower accuracy of Position and Attitude Measurement Device in InSAR system and puts forward a method of topographic change detection base on terrain matching.This is a new method in topographic change detection with InSAR data.It can improve the degree of automation data processing in topographic change detection with poor Direct Georeferencing of InSAR system.
