导弹无线电引信电磁脉冲效应仿真

Simulation of Electromagnetic Pulse effect to Missile Fuse

摘要:

以LFM导弹无线电引信为研究对象,以Ansoft软件为仿真平台,建立无线电引信天线模型和电路模型,通过计算机仿真对高功率微波(HPM)干扰导弹无线电引信的效应进行了研究。仿真结果表明,在高功率电磁脉冲作用下,混频器和滤波器上分布的电压很高,而进入执行级的电压很低,达不到启动电压的幅度。

Abstract:

Simulation model of LFM missile radio fuse including antenna and circuit was built based on Ansoft software. Research on high power microwave (HPM) impact to missile radio fuse was made by computer simulation. The result showed that by action of HPM the distributing voltage on mixer and filter was very high, but the voltage on executor was too low to satisfy the execution voltage.
