Microwave Attenuation and Phase Shift in Sand and Dust Storms

摘要：

　　Based on the forward scattering amplitude function for sand particle under the Rayleigh approximation, the calculation models of microwave attenuation and phase shift due to sand and dust particles is given in terms of lognormal size distribution The model shows that attenuation and phase shift are found to be dependent on visibility, frequency and complex dielectric constant.Obtained results show that moisture content of particle has significant impact on the attenuation and phase shift, and the higher frequency is, the greater are the influence on attenuation and phase shift.The attenuation and phase shift increase with the increase of moisture content.
