On the other hand, with the purpose of fuzzy feature extraction and fuzzy classification device design, the undulatory property of maximum and minimum scattering power corresponding respectively to the maximum and minimum eigen-polarization has been investigated in frequency domain. Furthermore, the anisotropy polarization degree of target, which is determined by both maximum and minimum scattering power of target, has been studied; meanwhile, the dynamic changing characteristic of eigen-polarization on Poincare polarization sphere has been investigated by means of the conception of polarization frequency stability, the research result shows that PSD value has a big jump near π, forming a sharp pulse, and different target has their individual distribution property of PSD pulse.

另外，围绕目标模糊特征提取及模糊分类器的设计，研究了目标最大、最小本征极化所对应的目标最大、最小散射能量随观测频率的起伏特性，考察了由目标最大、最小散射能量共同决定的目标的各向异性极化程度；同时，采用极化频率稳定度的概念，研究了本征极化在Poincare极化球面上的动态变化特性，在最大、最小散射能量相等的频率点上，PSD曲线呈现为幅度接近π值的尖锐脉冲，反映了目标极化散射结构对这一频率跳变极为敏感，但不同目标的这种PSD曲线特征又有很大的不同。
