炮射导弹发射电点火具电磁安全性分析

Electromagnetic Safety Analysis on Electric Igniter of Gun-Launched Missile

分析了强电磁脉冲对炮射导弹的耦合途径,利用传输线矩阵法(TLM)研究了强电磁脉冲对导弹的耦合效应。建立了导弹的实体模型,仿真得到了电场水平极化和垂直极化时,导弹内部发射电点火具位置的电场分布。建立了电点火具天线模型,仿真得到了该电点火具在敏感频率下的天线增益,进一步计算了发射电点火具在内部场的作用下耦合得到的最大接收功率,其值为3.05×10-6W,远小于该电点火具的最大不发火功率。

The coupling path of the intense electromagnetic pulse to gun-launched missile is analyzed and the trans- mission line matrix （TLM） method is utilized to study the corresponding coupling effect. The internal electric field distribu- tion of the missile due to horizontal polarization and vertical polarization is obtained by simulation through the establishment of the missile entity model. A dipole antenna model of launched electric igniter is set up and the antenna gain is obtained. For further study, the maximum radio frequency power into the launched electric igniter at a value of 3.05×10^-6W is calculated, which is much smaller than the maximum no-fire frequency power.
