摘要
研究了毫米波高分辨极化雷达的目标识别问题,提出了瞬态极化Wigner-Ville分布(WVD)的概念,导出了瞬态极化WVD莫耶公式,证明了瞬态极化WVD时频域相关与极化信号时域相关的等价关系.在此基础上,提出了基于高分辨极化雷达目标回波瞬态极化WVD相关的目标识别方法,并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 millimeter wave high resolution polarimetric radar was studied. The definition of instantaneous polarization Wigner Ville distribution(InPolWVD) was given, and its Moyal′s formula was derived, which implies the equivalence between the correlation of InPolWVDs in time frequency domain and the correlation of polarimetric signals in time domain. Then, a novel target recognition method was proposed based on the correlation of InPolWVDs. Experiments of demonstrating recognition with five kinds of aircraft targets were presented. The results show that it is an effective target recognition method of high resolution polarimetric radar.
