Abstract :
A verification of DEM generation using ultra-wideband interferometry is presented. The processing is performed iteratively by first generating a coarse resolution DEM applying a stereoscopic technique, and then refocus the interferometric image pair based on this output. In the latter step the DEM heights are refined using the coherence phase. The retrieved DEM is compared with an existing elevation model and a manually measured GPS ground profile
