Sentinel-1D Single Look Complex Product
The Sentinel-1D satellite was launched November 4, 2025. Sentinel-1D is the the latest satellite to be added to the Sentinel-1 constellation. The Sentinel-1 satellites (Sentinel-1A, Sentinel-1B, Sentinel-1C and Sentinel-1D) 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-1D Single Look Complex (SLC) data products consist of focused SAR data, geo-referenced using orbit and attitude data from the satellite, 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-1D products provided through the Copernicus Data Space Ecosystem.
Users are encouraged to review the plans for the transition to Sentinel-1D as it takes over Sentinel-1A duties at https://dataspace.copernicus.eu/news/2026-5-28-sentinel-1-orbital-reconfiguration-dates
