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.
