Advanced techniques for interferometric synthetic aperture radar data exploitation

Recent advances in the areas of phase history processing, interferometry, and radargrammetric adjustment have made possible extremely accurate data extraction from Synthetic Aperture Radar (SAR) imagery data. The potential gain from interferometric exploitation is significant since accuracy of measurements can theoretically be determined to within a resolution element of wavelength dimension. A unique combination of advanced techniques is described which has made possible more accurate extraction of metric position and elevation model data from multiple pass SAR. The unique approach outlined can be implemented on conventional stereo extraction workstations with appropriate refinements. This paper addresses the accuracy achievable from repeat passes of the ERS-1 platform. Experimental results are provided.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
