[PS2-2-2-3-2-3-3-1] Interferometric Wide Swath Mode

Interferometric Wide Swath Mode (IW) is the main acquisition mode of the Sentinel-1 satellites over land. For this mode, regular revisit times and a consistent long-term archive are ensured It uses the Terrain Observation with Progressive Scans SAR (TOPSAR) acquisition technique and acquires data with a swath width of 250km at a spatial resolution of 5 m by 20m.
