Abstract

A radiophysical complex is considered for studying the influence of the propagation environment on orthogonally linearly polarized electromagnetic waves with horizontal and vertical polarizations. The radiophysical complex made it possible to register the quadrature components of the received orthogonally polarized signals and to calculate the amplitudes and phases of the signals and their polarization characteristics from them. Electromagnetic waves were emitted with equal amplitudes, initial phases, and wavelengths from two points spatially separated in the horizontal plane. In the framework of the two-vibrator scattering model, an analytical expression for the scattering operator is obtained, which makes it possible to estimate the differential characteristics of the propagation medium. The relationship between the model parameters and the obtained experimental estimates of the polarization characteristics of the received orthogonally linearly polarized signals on a surface path with a length of 8 km is confirmed.

用于研究传播环境对正交偏振电磁波影响的辐射物理综合体

摘要为研究传播环境对具有水平和垂直极化的正交线性极化电磁波的影响，考虑了一种辐射物理复合体。该辐射物理复合体可以记录接收到的正交偏振信号的正交分量，并从中计算出信号的振幅和相位及其偏振特性。电磁波以相等的振幅、初始相位和波长从水平面上空间相隔的两点发射。在双振子散射模型的框架内，得到了散射算子的解析表达式，从而可以估算传播介质的微分特性。模型参数与在长度为 8 千米的表面路径上接收到的正交线性极化信号的极化特性的实验估计值之间的关系得到了证实。
