基于极化域能量谱的飞机目标识别

AIRPLANE TARGET RECOGNITION BASED ON ENERGY SPECTRUM IN THE POLARIZATION DOMAIN

本文导出了Ｐｏｉｎｃａｒｅ极化球大圆极化轨道上目标散射能量与极化态的正弦关系，结合宽带观测条件，定义了极化域能量谱的新概念，并利用五种飞机目标的宽带极化散射数据，提取了极化域能量谱特征，获得了良好的目标识别效果。

In this paper,the relationship between target's scattering energy and the incident polarization is derived on the greatcircle track on the Poincare Sphere.Considering the wideband measurement condition,the conception of energy spectrum in the polarization domain is defined.On the basis of energy spectrum,the polarization features of five kinds of airplane targets are extracted in the wideband and polarimetric case,and satisfactory recognition results are achieved.
