Web13 Oct 2024 · The main TOPS mode used by the Sentinel-1 satellites, known as Interferometric Wide-Swath, or IW mode, has three subswaths that between them cover a swath of 250 km on the ground, with a range of incidence angles between 30° and 45°. WebWe, therefore, propose a detection method applicable to Sentinel-1 extra wide-swath (EW) SAR scenes. Using intensity values coupled with incidence angle and noise-equivalent sigma zero (NESZ) information, the image segmentation method is able to detect the low backscatter targets as one segment across subswaths. grepolis addonsWebIn Sentinel-1 IW SLC products, you will find 3 subswaths IW1, IW2, IW3.
