| 摘 要： | 研究了高分辨极化雷达目标识别问题，给出了瞬态极化Wigner—Ville分布(WVD)的定义，提出了基于瞬态极化WVD相关的目标识别方法，以充分利用目标回波的极化信息，并且揭示了该方法的性能改善与目标回波极化散度之间的关系。最后利用五种飞机缩比模型外场测量数据进行了目标识别实验。实验结果表明，该方法是一种有效的高分辨极化雷达目标识别方法。

| Abstract: | 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. |
