| Abstract: | The INSAR uses the phase difference of the radar returns in two or more complex SAR images, acquired at separate times from a nearly exactly repeating orbit, to generate a digital elevation model (DEM) with a vertical resolution of a few meters and detect changes in the surface with a high resolution of only one centimeter. We first introduce the development of the INSAR. Then, we present the theory of INSAR and D INSAR and the procedure of data processing. Experiments have been carried out using ERS 1 data and the results demonstrate the feasibility of satellite INSAR technique. At last the applications of INSAR are introduced, which mainly include topographic mapping, geo hazards research, polar observation and ocean surface observation. |
