摘　　要：为提高在沙尘环境中毫米波传播预测的准确性,在抛物模型的基础上对传播损耗进行仿真。文中分析了沙尘的相对介电常数,根据能见度和maxwell公式计算其占空比,可以求得沙尘的等效介电常数,相比较传统经验模型,可以更准确地描述沙尘对毫米波传播产生的作用。将其应用于沙尘电波传播环境预测中,仿真结果显示,该模型能够反映沙尘对毫米波传播的影响,可以有效预测电波传播特性。In order to improve the accuracy of radio wave propagation prediction in sand dust environment,this paper propos⁃es a PE method to calculate the attenuation of radio wave in smoke and dust environment.In this paper,the relative dielectric con⁃stant of sand dust is analyzed,and the equivalent dielectric constant of battlefield dust can be obtained by calculating its duty ratio according to the visibility and maxwell formula.Compared with the traditional empirical model,the influence of sand dust on radio waves can be described more accurately.The simulation results show that the model can reflect the influence of sand dust environ⁃ment on the propagation of airwaves and can effectively predict the propagation characteristics of airwaves.
