Abstract—The technique of Interferometric Synthetic Aperture Radar can generate high precise Digital Elevation Model (DEM) fast, which makes it play a very important role in the development of social economy and construct of national defense. Once the high precise DEM can be acquired in real-time, the worthiness of the technique will be embodied fully. In this thesis, the research dynamic of generating DEM in real-time at home and abroad is discussed in detail, the characteristic of the several interferometric system at home and abroad acquired some progress in course of real-time interferometry processing is introduced, the key techniques in acquiring DEM in realtime are summarized and analyzed, and finally the development trend is discussed.
