Abstract
With ERS tandem data being today's primary interferometeric data source, DEM generation is currently limited to moderate terrain. In general, layover and shadow affect the visiblity and resolution of SAR sensors in rugged terrain. As a consequence, classification and phase unwrapping of such data is difficult. Shuttle Radar Topography Mission SRTM X-SAR data is expected to give better results due to its viewing geometry and the high coherence, but it might still suffer from the problem under extreme conditions. Here we perform a quantitative analysis of the radar illumination conditions, using a digital elevation radar model. The potential benefit of combing data from different viewing geometries like incidence angle and orbit inclination are shown.
