摘要
通过数值计算和试验研究地面附近有限长架空多芯电缆对高功率微波的耦合特性,为指挥工程中电缆耦合特性研究提供参考。数值计算和试验结果表明,架空多芯电缆对窄带高功率微波和超宽谱高功率微波具有耦合作用,不同芯线之间存在互耦,耦合特性受电缆接头处理方式、电缆长度、电缆类型、电缆与来波方向(极化方向)夹角、屏蔽层是否接地、微波频率等影响严重。数值计算和试验结果在规律上比较一致,证明了计算模型和试验方法的正确性和有效性。
The characteristics of a multi-core cable above a perfect ground coupling to non-nuclear EMP are studied through numerical simulations and experimental investigation,which can be benefit to research the cables coupling effects in command structure.The results of numerical simulations and experimental investigation indicate that a multi-core cable above a perfect ground can couple with narrow band and ultra-wide band HPM.Each core can couple with other cores and the coupling effects are decided by treating methods of the cable＇ s joints,length and type of cables,angle between cable and incoming wave（direction of polarization）,shielding layer grouding,microwave frequency and so on.The results of numerical simulations and experimental investigation are uniform in regularity,which proves the correctness and feasibility of mathematic mode and experimental method.
