Abstract

The distortions caused in conventionally focused TOPS SAR images which originate from the azimuth-variant Doppler centroid within a burst are presented and analyzed. In par- ticular, the azimuth distortions due to topography mismatch in focusing stages and the range distortions due to the as- sumption of validity for the stop-and-go approximation are expounded in detail. Compensation strategies to accom- modate the two effects in an accurate and precise manner are discussed and validated with TOPS data acquired with TerraSAR-X.
