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.

Key words: electromagnetic attenuation；aeolian sand；soil dielectric constant
