The Sentinel-1A and Sentinel-1B satellites, operated by the European Space Agency (ESA), carry synthetic aperture radar (SAR) instruments operating in the C-band, the spectrum taking in ...

Currently operated for Sentinel-1A and Sentinel-1B - but can be also aligned for other SAR missions. Over the years the Calibration Group has developed and built highly accurate transponders in ...

The closer the bands, the greater the motion. Seismologists use these visualizations to measure land deformation from earthquakes. Another type of SAR analysis, called polarimetry, measures the ...
