Sentinel-1 is a constellation of two spaceborne C-band synthetic aperture radar (SAR) sensors developed and operated by the European Space Agency under the Copernicus Earth Observation programme. This website is the result of the joint effort of Aresys and ESA to use Sentinel-1 data to map and classify the radio frequency interference affecting the C-band.
Starting from June 2019, two maps are produced for each S-1 orbit cycle (12days) of each sensor: an RFI probability map and an interactive RFI map showing the main events. Additionally the RFI database of each orbit cycle can be downloaded.
For further details about how the RFI maps are generated, please refer to the technical specification.
