摘　　要：Huynen目标参数和最佳极化(OPs)是极化信息处理中两个基本概念。最佳极化在Poincare球上的分布根据Huynen目标参数的特征角可以细分为“针型”、“帽型”和“叉型”三种形态,目前尚缺乏完善的讨论。本文基于Kennaugh矩阵推导了目标的最佳极化,讨论了Huynen目标参数与最佳极化的对应关系。然后,基于三种最佳极化的分布形态讨论了几种典型结构目标的极化特性,可以为雷达极化学研究人员建立更清楚的概念。Huynen Target Parameters(HTPs)and Optimum Polarizations(OPs)are two fundamental concepts in the polarization information processing field.According to the characteristic angle of HTPs,the graphical representation of OPs can be divided into three classes,needle shape,top shape,and the well-known fork shape,which has not been sufficiently discussed before.In this paper,OPs are derived based on the Kennaugh matrix.Then,the relationship between HTPs and OPs is revealed.On the basis of that,the polarization scattering characteristics of several typical structures are investigated.This paper aims to establish a clear concept about HTPs and OPs for radar polarimetry researchers.
