摘　　要：根据电磁波在分层介质中阻抗匹配原理,计算了非均匀非磁化等离子体平行与垂直极化波的功率反射系数。基于碱金属盐的高温电离特性,以功率反射系数为研究对象,对雷达无源诱饵用等离子体的厚度、温度和电子密度分布等参数选择进行了分析,并根据所选择的参数讨论了入射角对无源诱饵应用的影响。According to the impedance matching mechanism when incident microwave transmit in the non-uniform substance,the total wave energy reflectance calculating method of TE wave and TM wave on the surface of plasma was introduced in this paper.The choices of the thickness,temperature and distributing of uncontrolled electron of plasma used for radar passive decoy were studied according to the total wave energy reflectance based on the ionization specialty of the compound alkali metals.And according to the parameters of plasma chosen above,the application impact of radar passive decoy was analyzed under various incidence angle of microwave.
