摘　　要：根据等离子体三波相互作用中慢空间电荷波与散射电磁波的相位匹配关系．采用PIC粒子模拟方法，分析了漂移等离子体中影响散射电磁波相对于入射电磁波的频移变化因素．为控制散射电磁波频移实现等离子体变频调谐隐身提供可行的技术途径。Based on the phase matching relation between space charge wave and the scattered EM wave in three wave interactions, the effect of frequency shift characteristic of the scattered EM wave on the incident wave was investigated by particle simulation. The results provide a feasible technique way of stealth of plasma by frequency shift.
