TOPSAR: Novel Radar Technique Sentinel-1 uses a cutting-edge SAR technique known as Terrain Observation with Progressive Scans SAR (TOPSAR). https://youtu.be/pLN8bGd7-Yw As this video illustrates, like standard ScanSAR, TOPSAR sends and returns radar data to and from sub-swaths that together comprise one wide swath. The difference is that TOPSAR’s radar also scans back and forth along …

The Sentinel-1 SAR observation plan implements a baseline pre-defined mission observation scenario, making optimum use of the SAR duty cycle within the technical constraints of the overall system. This scenario aims at fulfilling, during the routine exploitation phase, the observation requirements of the Copernicus services and of ESA/EU member states. In addition, on a best …
