Effects of humidity on sand and dust storm attenuation predictions based on 14 GHz measurement
Several models were proposed to predict the attenuation of microwave signals
due to sand and dust storms. Those models were developed based on
theoretical assumptions like Rayleigh approximation, Mie equations or
numerical methods. This paper…
