极化雷达测量目标的完整散射矩阵。对于森林和其他自然目标，平均回报通常是部分两极分化的。导出了散射矩阵的二阶统计量为全极化的条件，并证明了这些条件与协方差矩阵的本征值有关。这一分析的结果是一组三个量，它们表示散射体产生非极化分量的能力。这些数量的森林面积显示。>；
A polarimetric radar measures the complete scattering matrix of a target. For a forest and other natural targets, the average return is, in general, partially polarized. Conditions on the second-order statistics of the scattering matrix under which the return is fully polarized are derived, and it is shown that these conditions are connected with the eigenvalues of the covariance matrix. The result of this analysis is a set of three quantities which indicate the ability of a scatterer to generate an unpolarized component. These quantities for forested areas are shown. >
