为了研究炮射导弹在飞行状态下的电磁能量耦合规律,利用传输线矩阵法(TLM)分析了强电磁脉冲对飞行状态下导弹的耦合效应;通过建立导弹实体模型,改变入射角度和电场极化方向,得到了电磁脉冲对导弹的电磁能量耦合规律。结果表明:入射波垂直导弹中心轴入射的情况下,电场水平极化耦合到弹体内部的场强幅值比垂直极化和45°极化时的场强幅值大;当入射波入射方向变化时,导弹内部耦合场的变化明显。

To analysis the electromagnetic energy coupling way of gun-launched missile in flight state, the transmission line matrix (TLM) method was utilized to study the coupling effect of electromagnetic pulse in in-flight missile. The coupling law of electromagnetic pulse for missile was obtained by establishing the missile entity model and changing the incident angle and polarization direction of the electromagnetic pulse. The studies indicate that when the incident angle of the incident wave is vertical to missile center axis, the missile internal electric field strength amplitude produced by horizontal polarization wave is larger than what produced by vertical polarization wave and 45 °polarization wave, and the changes of incident direction have an obvious influence on missile internal coupling field.
