摘要

本文给出了在给定相关函数下产生介电常数随机场的方法。结果来自于波场的平均强度和空间相关函数的模拟建模，到达角的色散，以及通过介电常数随机不均匀层传播的波的振幅和相位的空间相关函数。用摄动法近似公式计算无线电波波动特性的结果与仿真建模结果进行了比较。

Simulation modeling of statistical characteristics of the radio wave in a layer with random inhomogeneities of dielectric permittivity

This paper presents the methods of generation a random field of dielectric permittivity with a given correlation function. Results are derived from performing a simulation modeling of the mean intensity and a spatial correlation function of the wave field, the dispersion of angles of arrival, and spatial correlation functions of the amplitude and phase of the wave that has propagated through a layer with random inhomogeneities of dielectric permittivity. A comparison is made of the results of calculations of fluctuation characteristics of the radio wave by approximate formulas obtained with the perturbation method with the results of simulation modeling.
