【摘要】 风沙天气对人们生活有很大影响,其中一方面就是对电磁信号传播的干扰,文中通过建立基本地形模型,将风沙天气进行建模处理,加入到基本地形模型中,然后研究其电磁特征参数得到电磁模型,对比研究了在没有风沙情况下的电磁传播衰减以及不同严重程度风沙天气中的电磁传播衰减。所得规律既可以为进一步研究风沙区域电磁信号衰减问题提供技术参考,也可以由衰减情况反推出风沙天气的严重程度。更多还原

【Abstract】 Sandstorm weather has a great influence on people’s life,one of which is the interference of electromagnetic signal transmission,this article will establish the basic terrain model,and the Sandstorm weather simulation modeling processing,add to the basic terrain model,and then study its electromagnetic characteristics parameters to get a simulation model,At last,the propagation attenuation of electromagnetic wave in the absence of sand and the attenuation of electromagnetic wave propagation in different severity are compared by simulation. The attenuation diagram can be used to provide reference for considering the attenuation of the electromagnetic signal in the sandstorm area,and can be used to reverse the severity of the sandstorm weather.更多还原
