Abstract

Derivation of the relation called the 'reversal' transformation, joining matrices in the two alignments, is presented. To arrive at the solution, a concept of 'polarization and spatial phase' vectors for antennae and waves, different from complex antenna heights and complex wave amplitudes, has been applied. For Sinclair and Jones matrices, describing the same physical phenomenon of nondepolarizing scattering, two different Poincare/spl acute/ sphere models have been proposed based on decomposition of a Sinclair matrix into two transformations of inversion and rotation of the Poincare sphere of incident polarizations. For the Jones matrix model another Sinclair matrix has been determined followed by an additional orthogonality transformation. Such a difference in construction of the two models can explain diverse physical interpretations of their operation. Limited number of simple formulae describing scattering will be obtained when applying to radar polarimetry a special 'engineering approach' introduced in the paper.

从传播和传输的角度分析了极化SAR信号的各种解释的可能性

推导了称为“反转”变换的关系，将两个排列中的矩阵连接起来。为了得到解决方案，应用了不同于复杂天线高度和复杂波幅的天线和波的“极化和空间相位”矢量的概念。对于描述相同的非去极化散射物理现象的Sinclair矩阵和Jones矩阵，基于将Sinclair矩阵分解为入射偏振的庞加莱球的反转和旋转两种变换，提出了两种不同的庞加莱/spl急性/球模型。对于琼斯矩阵模型，确定了另一个辛克莱矩阵，然后进行了额外的正交变换。这两种模型在构造上的差异可以解释其运行的各种物理解释。本文介绍了一种特殊的“工程方法”——雷达偏振测量，当应用于雷达偏振测量时，会得到有限数量的描述散射的简单公式。
