| Abstract: | InSAR(Interferometric Syntheic Aperture Radar) is a new microwave remote sensing technique with great developing potential.It can be applied to form DEM(Digital Elevation Model),mapping and monitoring minor terrestrial deformation in large area.In this paper,considering the reference surface,terrain and surface deformation,the interferometric phase decomposition in InSAR is analyzed and discussed from geometry point,and the relevant function expressions of specific phase components are presented.Then the basic principle of generating DEM and acquiring deformation is described.Finally,taking JERS and ENVISAT data as example,application and process of DEM formation and earthquake deformation field abstraction are displayed. |
