Abstract A model for the decomposition of polarimetric SAR data is developed in this paper. The model is assumed to consist of four backscatters: Bragg scatter, double-bounce scatter, odd-bounce scatter and volume scatter. This scattering model can successfully describe the mechanism of man-made and nature targets to scatter the incident electromagnetic wave. Using NASA/Jet Propulsion Laboratory (JPL) AirSAR data, the model has been tested, the result shows that, the model can describe the mechanism of polarimetric backscatter from buildings and vegetated areas quite well.
