| Abstract: | The essential principles of Interferometric Synthetic Aperture Radar (InSAR) and Differential InSAR
(D- InSAR)are demonstrated in this paper. As for obtained achievements from abroad in -recent
years, the possibility of D- InSAR applications in urban subsidence measurements is emphatically
discussed. Methods to acquire SAR data are enumerated and current progresses as well as application
future of InSAR are also discussed afterwards. |
