This collection contains Sentinel-1 Level-1 Single Look Complex (SLC) products which consist of focused SAR data that are geo-referenced using orbit and attitude data from the satellite, and provided in slant-range geometry. Sentinel-1 is a polar-orbiting, all-weather, day-and-night C-band radar imaging mission funded by the European Union and carried out by the ESA within the Copernicus Programme, consisting of a constellation of two satellites.

The Sentinel-1 Level-1 SLC products include a single look in each dimension using the full available signal bandwidth and complex samples (real and imaginary) preserving the phase information. The products have been geo-referenced using the orbit and attitude data from the satellite and have been corrected for azimuth bi-static delay, elevation antenna pattern and range spreading loss.
