The reason is this: Beta0, also called radar brightness, is the basic calibration of a SAR product. It makes use of an internal calibration constant stored in the metadata. You use it if you don’t have information on the incidence angle (red angle) of your image. The incidence angle is defined as the angle between the surface vertical of the earth (without terrain) and the incoming signal. [image] Sigma0, the normalized radar cross-section, is an advanced measure of calibration. It takes int…
