Embodiment Construction
[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0044] Refer to attached figure 1 . The specific implementation steps of the present invention are further described in detail.
[0045] Step 1: Input the polarimetric SAR image to be classified and the corresponding polarimetric SAR SAR real object classification.
[0046] Step 2, remove coherent speckle noise.
[0047]The refined Lee filtering method with a filter window size of 7×7 is used to filter the polarimetric synthetic aperture radar SAR image to be classified to remove coherent speckle noise, and obtain the filtered polarimetric synthetic aperture radar SAR image.
[0048] Step 3, feature extraction.
[0049] From all the pixels in the filtered polarization synthetic aperture radar SAR image, select all the pixels containing real object marks to form a set of pixels with real object marks.
[0050] Calculate the modulus values of the 6 data ...
