Abstract

An algorithm for DEM generation using ultra-wideband interferometry is described. Results based on VHF-band data acquired by the CARABAS airborne SAR system is presented at a spatial ground pixel resolution of 16×16 m. The resulting DEM shows good agreement with topographic map. The results indicate good potential for topographic mapping of the true ground surface
