Paper Abstract

The SAR interferometric technique, in particular using the ERS-1 data, already proved to be an effective method to extract DEM. However, the detail analysis of the accuracy and artifact level in the generated DEM tends to lower the initial expectations and reveal the need, far more than for optical stereoscopy, to understand the imaged scene. Actually some scene analysis is necessary to desambiguate phenomena conveyed by the phase signal although in return these informations may improve our understanding of the scene. Therefore we will present the use of a priori knowledge in the SAR interferometric DEM generation and how the interferometric product can then be used to improve our scene analysis. In particular we show here that from interferometric products one can generate good quality geocoded radar orthoimages which then allow easier scene interpretation.
