Abstract:
The TerraSAR-X mission launched in June 2007 provides brilliant SAR products in several different modes ranging from high resolution spotlight, with 5 km x 10 km scene coverage, up to ScanSAR acquisitions, with 100 km swath width. For ice and oceanographic applications there is a demand for even larger coverage. This paper describes the development of the new recently implemented and released WideScanSAR mode with swath widths between 190 km and 260 km, depending on the varying incidence angles. Furthermore, the optimization of the swaths and beams for all orbit heights is shown and first SAR image evaluations are presented.
