The invention relates to a cross-scattering model-based polarization
radar remote sensing image urban target
decomposition method. The method includes the following steps that: a PolarSAR image single-view
polarization scattering matrix is converted into a polarization
covariance matrix or a polarization coherence matrix; a PolarSAR image pixel polarization
azimuth is calculated on the basis of the polarization
covariance matrix or the polarization coherence matrix; the cross-scattering model of a building is constructed on the basis of the polarization
azimuth and a
dihedral angle reflector;a polarization target
decomposition solving equation is constructed according to a surface scattering model, an even-order scattering model, a
volume scattering model, a spiral scattering model and the cross-scattering model, and the scattering coefficients of each model are solved; and the scattering weighting coefficients of each model are corrected, and surface scattering power, even-order scattering power,
volume scattering power, spiral scattering power, and cross-scattering power are calculated on the basis of the scattering weighting coefficients of each model, and target decompositionis completed. With the cross-scattering model-based polarized
radar remote sensing image urban target
decomposition method of the present invention adopted, the HV scattering of the building can be effectively described.
