摘要

为客观评价某型米波无线电引信的抗电磁脉冲（EMP）干扰能力

构建了引信电磁脉冲辐照效应试验系统

开展了超宽带电磁脉冲（UWBEMP）、核电磁脉冲（NEMP）、雷电电磁脉冲（LEMP）辐照效应试验

分析了受试引信的效应规律和失效机理。试验结果表明:在电磁脉冲辐照条件下

受试引信最敏感受试姿态为引信装定孔正对天线

弹体方向与电场方向平行;主要能量耦合通道为弹体;一定参数的UWBEMP和NEMP可以造成引信意外发火

而LEMP不能造成引信发火;重复频率越高

电磁脉冲对引信的干扰能力越强

同为70 kV/m的UWBEMP辐照场强

单次、10 Hz重频、20 Hz重频和50 Hz重频触发条件下引信的发火率分别约为20%、60%、80%、100%;晶闸管（SCR）为电磁脉冲作用下引信执行电路的敏感器件;受试引信的失效机理为:辐射能量通过弹体耦合到执行电路电源端

耦合电压瞬态变化率超过了晶闸管断态电压临界上升率而使晶闸管导通

进而导致引信意外发火。

Abstract

To evaluate the anti-electromagnetic pulse（EMP） jamming capability of a certain metric wave radio fuze

we constructed an experiment system for fuze EMP irradiation

and performed experiments under ultra-wide band electromagnetic pulse（UWBEMP）

nuclear electromagnetic pulse（NEMP） and lightning electromagnetic pulse（LEMP） irradiation.Meanwhile

we analyzed the effect rules and failure mechanism.Experimental results show that

in EMP irradiation

the strongest coupling pose is that the setting aperture is toward to the antenna and the bomb body is parallel to the electric field direction.Bomb body is the main energy coupling channel.UWBEMP and NEMP with a certain parameters can make fuze fire

but LEMP can not.The higher the repetition frequency is

the stronger the interference capability of EMP will be.On 70 kV/m field strength of UWBEMP

the firing rate of the repetition frequency in single

10 Hz

20 Hz

and 50 Hz states are 20%

60%

80% and 100%

respectively.Silicon controlled rectifier（SCR） is the sensitivity device of the executive circuit.The failure mechanism of fuze is that the irradiation energy couples to the power in the executive circuit through the bomb body

because the changing rate of the coupling voltage exceeds the critical changing rate of SCR

leading to the miss-action of the fuze.
