| Abstract: | Traditional target's optimal polarization theory was based on the scattering matrix.But the scattering matrix is usually difficult to obtained.Thus,the calculating process always is complex.In this paper,we deduce the formulae optimal receive power based on Stokes matrix and polarization synthesis.The algorithm could easily be carried out and the programming process is much directly.The experimental results show that the ideal results could be obtained by the proposed algorithm. |

| Keywords: | target optimal polarization polarization synthesis Stokes matrix Kennaugh's optimal polarization |
