采用等离子体粒子模拟方法,探索无界漂移等离子体中空间电荷波与电磁波所发生的非线性波-波相互作用,时应用这一相互作用过程所产生的散射波的频移特性,寻找产生最大限度频移的散射波物理途径以及实现这一过程对等离子体参数的技术要求.详细讨论等离子体影响散射电磁波频率特性的物理因素及产生隐身的原因.%The PIC plasma particle simulation method is used to invcstigate the proccsses of nonlinear wave-wave interactions among incident electromagnetic wave, the slow space charge wave and the scattered electromagnetic wave in the drift plasma. In order to find out the plasma parameters that cause the maximum frequency excursion of the scattered electromagnetic wave, the characteristics of the frequency excursion of the scattered electromagnetic wave caused by such interactions and the factors to affect them are especially discusscd.
