摘　　要：研究了湍流和尘暴构成的随机介质系统对电磁波传播的影响,得到了电磁波衰 减,相移与交叉极化效应的公式;结果表明:尘暴主要影响圆极化波的交叉极化分辨率和 电磁波的相移,大气湍流主要对电磁波产生衰减效应。Dust storms and turbulence consist of a random medium system, its effects on electro- magnetic wave propagation are studied. Attenuation of electromagnetic wave, its phase shift and cross- polar discriminition XPD are presented. Results show that dust storms mainly effects XPD and phase shift of electromagnetic wave, turbulence chiefly produces attenuations.
