The AIRSAR/TOPSAR integrated multi-frequency polarimetric and interferometric SAR processor

The algorithms and implementation of an integrated SAR processor designed to process multi-frequency SAR data from either polarimetric, interferometric or mixed mode (a combination of polarimetric and interferometric modes) SAR systems is described. The processor is designed to automatically produce co-registered multi-frequency images regardless of the data collection mode at different frequencies. If at least one frequency interferometric DEM is available, all images are resampled and terrain corrected using the DEM. Examples are provided and discussed.
