TOPSAR is a recently proposed SAR mode for wide swath acquisition, which is intended to replace the conventional ScanSAR mode. TOPSAR will be used by the ESA Sentinel-1 SAR sensor in its main interferometric wide swath mode. TerraSAR-X has demonstrated the TOPSAR mode in space by acquiring and processing TOPSAR images for the first time. The paper reports the results of the image scalloping analysis performed on TOPSAR, inverse TOPSAR and ScanSAR images.
