This paper proposes a new imaging algorithm based on a novel accurate range model to process the data acquired by Geosynchronous-Earth-orbital Synthetic Aperture Radar (Geo-SAR). The new range model, called DRM-5, is obtained from the 1–5th order Doppler parameters of spaceborne SAR. It is employed to describe the slant range of Geo-SAR during the(More)
During mapping a big area consisting of several interferometric SAR (InSAR) scenes, joint calibration procedure is proposed in this paper in order to achieve the accurate three-dimensional location and backscatter, and ensure their continuity among adjacent scenes. The proposed procedure contains geometric calibration and backscatter calibration. Geometric(More)
