  • In order to overcome the insufficiency of traditional algorithms in multi-target enhancement and polarimetric signature preservation, a new method is proposed to enhance targets in polarimetric SAR imagery. Based on the similarity parameter between target scattering matrix and surface scattering matrix, the coherency matrix of random target corresponding to different scattering mechanisms is multiplied by relevant real coefficient, thus it enlarges the otherness between surface scattering targets and other scattering targets. As coherency matrix is operated as a whole in this method, it does not change the relationship between the elements of coherency matrix and then preserves polarimetric information in SAR imagery. Utilizing fully polarimetric data obtained by SIR-C/X-SAR to test this method, the result is satisfactory.
