Sentinel-1A Single Look Complex Product

Published by ASF;ESA/CS1CGS | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 02:00 PM | Dataset Last Updated: June 23, 2026
Sentinel-1A, the first satellite in the Sentinel-1 constellation, was launched April 3, 2014. The Sentinel-1 satellites (Sentinel-1A, Sentinel-1B, and Sentinel-1C) are sun-synchronous polar-orbiting satellites that operate day and night performing C-band synthetic aperture radar (SAR) imaging. The Sentinel-1 satellites operate in four imaging modes with different resolutions (down to 5 meters) and coverage (up to 400 kilometers). The Sentinel-1 satellites provide dual polarization capability and short revisit times. Sentinel-1A Single Look Complex (SLC) data products consist of focused SAR data and are provided in slant-range geometry. Slant range is the natural radar range observation coordinate, defined as the line-of-sight from the radar to each reflecting object. The products are in zero-Doppler orientation, where each row of pixels represents points along a line perpendicular to the sub-satellite track. The 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 satellite’s orbit and attitude data and have been corrected for azimuth bi-static delay, elevation antenna pattern, and range spreading loss. The data products in this collection mirror the Sentinel-1A products provided through the Copernicus Data Space Ecosystem.
