[0036] The technical content and effects of the present invention will be described in further detail below with reference to the accompanying drawings.
[0037] Reference figure 1 , The implementation steps of the present invention are as follows:
[0038] Step 1. Pre-processing the polarized synthetic aperture radar SAR data.
[0039] Read the coherence matrix T of the polarized synthetic aperture radar SAR data, and perform Lee filtering on the coherent matrix of the polarized synthetic aperture radar SAR data to obtain the coherence matrix of the filtered polarized synthetic aperture radar SAR data;
[0040] Extract the Pauli feature of the polarized synthetic aperture radar SAR data, and synthesize the color image of the polarized synthetic aperture radar SAR according to the Pauli feature. The coherence matrix of the polarized synthetic aperture radar SAR data is a 3*3*N matrix, and N represents polarization. The total number of pixels of synthetic aperture radar SAR, each pixe...
