The problem of target recognition with high-resolution polarimetric radar is focused on in this paper. After the definition of instantaneous polarization Wigner-Ville distribution (InPol WVD) is given, a novel target recognition method which exploits the polarization information of target return, is proposed based on the correlation of InPol WVD, and the relationship between the improvement of this method's performance and target return's polarization divergence is demonstrated too. Recognition experiment of five kinds of aircraft targets is carried out, which shows that the recognition method presented here is effective.
