“…The 0 convention provides the natural radar observable [4], normalising simply by the areal sample interval in the slant range plane -the contents of images conforming to its convention are not subjected to modifications based on ellipsoid or terrain Earth models. Typical 0 and 0 conventions normalise by a standard area calculated using an ellipsoidal Earth model.…”

“…For distributed targets, radar brightness β 0 is defined as averaged backscatter ratio per unit area in the image plane (i.e., the slant range plane) [31]; backscatter coefficient σ 0 is defined as averaged backscatter ratio per unit ground area. For flat areas, the backscatter coefficient σ 0 can be retrieved using [17] incident angle θ…”

“…Using the energy rather than the peak intensity implies that, for a homogeneous distributed target, the ensemble average of the pixel intensity (i.e., for every pixel) equals the radar brightness divided by 4 . The radar brightness in turn equals sigma-naught divided by sine of the local incidence angle [22]. The above definition of radiometric calibration is related to the well-known integral method, [23].…”
