Sentinel-1B Single Look Complex Product Metadata

Published by ASF;ESA/CS1CGS | National Aeronautics and Space Administration | Catalog Last Checked: June 09, 2026 at 08:42 PM | Dataset Last Updated: June 08, 2026
Sentinel-1B, the second satellite in the Sentinel-1 constellation, was launched April 25, 2016. 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. The spacecraft experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data on 23 December 2021, as a consequence, ESA and the European Commission announced the end of the Sentinel-1B mission on August 3, 2022. Sentinel-1B 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 products in this collection are ISO compliant XML metadata created by the Alaska Satellite Facility Distributed Active Archive Center from the associated Sentinel-1B SAFE format product.
