Embodiment Construction
[0032] Reference figure 1 The specific implementation steps of the present invention are as follows:
[0033] Step 1. Read in a polarized SAR image to be classified, and perform Freeman decomposition on each pixel in the image to obtain three scattering powers P s ,P d ,P v , Where P s Represents the surface scattering power, P d Represents dihedral scattering power, P v Represents volume scattering power.
[0034] 1a) Read in each pixel of the polarized SAR image, and each pixel is a polarization covariance matrix C with 9 elements;
[0035] C = | S HH | 2 > 2 S HH S HV * > S HH S VV * > 2 S HV S HH * > 2 | S HV | 2 > 2 S HV S VV * > S VV S HH * > 2 S VV S HV * > | S VV | 2 > - - - 1 )
[0036] Among them, H means horizontal polarization, V means verti...
