摘要

本文介绍了瞬态极化时频分布的概念

并给出了瞬态极化Wigner-Ville分布及伪Wigner-Ville分布的定义

用以刻画雷达目标回波在时频域上的极化特性.然后

由回波的瞬态极化伪Wigner-Ville分布各分量的奇异值组成特征矢量

以BP神经网络作为分类器进行了目标识别实验.实验结果表明

与传统的对目标极化回波的两个分量分别作时频分析的处理方法相比

文中方法具有更好的目标识别性能.

Abstract

This paper introduces the concept of instantaneous polarization time-frequency distribution(InPol TFD)

and presents the definition of instantaneous polarization Wigner-Ville distribution(WVD) and pseudo Wigner-Ville distribution(PWD)

which are used to describe the polarization property of radar target's return in time-frequency domain.Next

a feature vector

formed by the singular values of each component of the InPol PWD of target's return

is used as input vector for the classifier based on BP neuron network.The target recognition results show that the proposed method has better performance than conventional one.
