APPLICATION OF INSAR TECHNOLOGY IN GEOGRAPHICAL SITUATION MONITORING
Keywords: InSAR, Geographical situation monitoring, D-InSAR, The terrain Deformation, Interference figure, Application
Abstract. In this paper, based on the geographical situation monitoring project of the earthquake zone of ludian county, zhaotong city, yunnan province,using the data of the radarsat-2 satellite (time frame is 20140304–20150416), InSAR technology is used to monitor the topography of the earthquake zone(about 420 square kilometers of monitoring area). Through the analysis of topographic deformation results, the scope of the terrain change is obtained, and the application and problems of InSAR technique in topographic geomorphological monitoring are discussed.
