Radiometric Comparison within the Sentinel-1 SAR Constellation over a Wide Backscatter Range
Radiometric calibration adjusts the measured pixel intensity to a physical property, the radar cross section (RCS).After calibration, this relationship here is defined over the entire backscatter range: from low image power (near noise) up to high reflections (below saturation).Based on a proper radiometric calibration, the measured radar backscatt
