Distinguish method of polarimetric complicated modulation decoy

The polarimetric complicated modulation decoy can fake real target in time,frequency and polarization domain,which make the traditional polarimetric distinguish method ineffective.Using the independent waveform modulation ability of two polarization transmitting channels of simultaneous polarization measurement radar,a distinguish method of the polarimetric complicated modulation decoy based on frequency transformation is proposed in this paper.After analyzing the algorithm of the polarization scattering matrix measurement of simultaneous polarization measurement radar and the theory of polarimetric complex modulation decoy,the distinguish method of the polarimetric complicated modulation decoy based on frequency transformation is introduced.The optimal detection algorithm of the real target based on this method is explained.Finally,the method is testified by experiment data.
