Paper Abstract

Recent advances in the areas of phase history processing, interferometric SAR (IFSAR) processing algorithms, and radargrammetric adjustment have made it possible to extract extremely accurate Digital Elevation Model (DEM) information from SAR images. Results of tests using recent improvements by the authors in the phase unwrapping and interferogram conditioning steps show that it might be possible to obtain good elevation accuracy from noisy interferograms resulting from foliage or extreme terrain. Results of ERS-1/ERS-2 Tandem data are presented.
