  • A novel scheme of target enhancement in high resolution polarimetric SAR imagery is proposed in this paper, which is based on the improvement of polarization characteristics similarity between pixels of the same region in the high resolution POL-SAR imagery. Huynens decomposition, polarization orientation angle extraction and a further angle rotation transformation are employed to eliminate the effect of the speckle noise and random vector scattering on each pixels polarization characteristics. Comparing with the existing target enhancement methods, the novel scheme can improve the polarization characteristics similarity of the pixels in the same region to get a promising target enhancement effect. The validity of the novel method is indicated by experimental results with fully polarimetric SAR data sets.
