The sand and dust attenuation has a great effect on the microwave propagation in the air. The calculation model of the sand and dust attenuation was got, combining the formula of the complex dielectric constant of dry sand with the dielectric constant of water. The model analysed the attenuation of sand and dust produced by explosion, vehicle and nature, and simulated attenuation rate of sand with different content of water. The result of numerical calculation shows that natural sand and vehicular sand have little effect on microwave when the frequency is not very high, but the attenuation of explosive sand could not be ignored. It also shows the attenuation of explosive sand rises quickly along with the increase of water content. This effect reaches saturated state when the humidity range
