摘要

雾是影响毫米波通信系统性能的典型气象条件之一.针对传统经验模型无法精确预测多径效应下的电波传播问题，给出了基于抛物方程的雾衰减预测模型.以自由空间雾特征衰减的预测为例，将本文模型与Rayleigh近似及经验模型的计算结果进行对比，验证了该方法的可靠性.最后将该模型应用于预测35 GHz和94 GHz毫米波在分别含有平流雾和辐射雾的复杂环境中的传播特性，仿真结果表明该模型有效地反映了地形绕射、地表反射等对电波传播的影响，为快速准确地预测复杂地理环境及特殊气象条件中的电波传播特性提供了一种有效的预测模型.

Abstract

Fog is one of the crucial factors in determining the performance of millimeter-wave communication systems.Because of the fact that the multipath propagation is not be taken into account by the traditional empirical formulae

this paper developed a parabolic equation model for estimating fog attenuation.The fog attenuation rate predicted by the model agrees well with that obtained by the Rayleigh approximation and an empirical formula

which verify the accuracy of our method.Finally

the model is applied to simulate the propagation characteristics of millimeter-wave at frequency of 35 GHz and 94 GHz in Advection fog and Radiation fog with complex environments

respectively.The results demonstrate that the model can take account of wave diffraction and reflection

and thus our scheme provides an efficient numerical method for computation of the propagation characteristics of millimeter-wave in complex environments.
