以宽带极化雷达体制为背景，定义了极化频率稳定度的概念。按极化状态在坡印卡勒（ｐｏｉｎｃａｒｅ）极化球上的动态分布信息，提取了目标的极化特征。对五种飞机目标进行了识别实验研究，取得了优良的目标分类或识别效果
Based on the broadband polarization radar system, the concept of polarization frequency stability is defined. According to the polarization state information on the poincare polarization sphere, the polarization characteristics of the target are extracted. Five kinds of aircraft targets were identified experimental study, and achieved excellent target classification or recognition effect
