摘　　要：分析了时变非磁化等离子体的隐身作用。研究了时变等离子体对入射电磁波的频率上移 ,这将使雷达回波的频率偏离开敌方接受回波的频谱范围 ,使目标的RCS减小。同时 ,给出了时变等离子体对入射电磁波的碰撞衰减并计算了时变等离子体对电磁波的反射系数。This paper presents the target stealth by using time-varying switched plasmas. The frequency upshifting of incident electromagnetic wave by a rapid creation plasma is examined. The frequencies of echo of electromagnetic-wave depart from the spectrum of receivable frequencies. The reduction of the RCS of a target is investigated. And besides, the paper describes the collisional absorption of EM waves in time-varying switched plasmas. And the reflection coefficients of EM wave are computed.
