The Airsar/topsar Integrated Multi-frequency Polarimetric and Interferometric Sar Processor

Research on the utility of Synthetic Aperture Radar (SAR) data in many diverse applications has seen great activity in the past decade. In particular, two powerful SAR techniques emerged during this time. Polarimetric SARS were frost demonstrated during the 1980’s and is described by van Zyl et al. [1] and Zebker et al. [2]. Since then polarimetric SAR data have been applied to most disciplines of Earth Science. A recent summary of these investigations can be found in [3]. The second powerful SAR technique that has received much attention lately is SAR interferometry. While fust published by Graham [4] in the 1970’s, interest in this technique has steadily increased since the demonstration of SAR interferometry using digital processing [5]. For a summary of the different applications of SAR interferomeq, please see [6].
