Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings.
[0037] refer to figure 1 , the concrete steps that the present invention realizes are as follows:
[0038] Step 1, input the coherence matrix of the polarimetric SAR SAR image to be classified.
[0039] Step 2, compensating the polarimetric SAR SAR coherence matrix.
[0040] Take the polarization azimuth angle for the polarization synthetic aperture radar SAR coherence matrix, use the polarization azimuth angle to calculate the rotation matrix of the polarization coherence matrix, use the rotation matrix to perform rotation transformation on the coherence matrix, and obtain the compensated polarization coherence matrix, the specific operation Proceed as follows:
[0041] The first step is to calculate the polarization azimuth angle of the polarization synthetic aperture radar SAR coherence matrix according to the following formula:
[0042]
[0043] Among them, ...
