Abstract
This article describes a radargrammetric chain for which each step tends to be specific to SAR imagery. First, we start with two complex images acquired in radargrammetric conditions and for which the parameters of the geometric view models are refined. The images are then turned into epipolar geometry while keeping their complex feature. Afterwards a multiresolution method of registration of the two images is used that takes into account a geometric criterion as well as the radiometry specific to SAR images. Finally, a DEM and two orthoimages are computed by spatiotriangulation from the previously found matches and from the geometric view models of the original images.
