Are you interested in getting the SAR scattering mechanisms from different scattering targets over the globe when prior information on the type of scatterer is not available? You may follow our recently published model free three component decomposition technique. This technique does not consider any prior information on the type of scatterer. Alongside this, the scattering power components are roll invariant due to which the users will not have to worry about the target orientation with respect to the radar line of sight. The results are very promising and could be applied in geophysical parameters estimations like agriculture, snow cover, forest etc.
