Sentinel-1
A C-band Synthetic Aperture Radar (SAR) satellite operating under the European Space Agency (ESA) Copernicus Programme. It enables all-weather, day-and-night Earth surface observation through cloud cover, providing dual-polarization data (VV and VH) at a spatial resolution of 10 metres.
Timeline (last 90 days)
Sentinel-1 is a C-band synthetic aperture radar satellite under the European Space Agency's Copernicus program, with active microwave imaging capability that does not depend on illumination and can penetrate clouds.
Fodder Watch uses Sentinel-2 (10-meter resolution, 5-day revisit) as the optical channel, Sentinel-1 C-band SAR as the cloud-penetrating radar channel, and Landsat 8/9 (combined 8-day revisit) for historical baseline time series.
Sentinel-1 satellites operate in dual-polarization mode, simultaneously acquiring data in both VV (vertical transmit–vertical receive) and VH (vertical transmit–horizontal receive) polarizations; VV is more sensitive to surface scattering from soil, while VH responds more strongly to volumetric scattering from vegetation.
Sentinel-2 provides red and near-infrared band imagery at 10-meter resolution, which closely matches the spatial resolution of Sentinel-1's SAR data.
