摘　　要：为满足实验需求,研制了一台小型的垂直极化偶极子型辐射波EMP模拟器。该模拟器天线是架高为5 m,半锥角为32°的倒立圆锥结构,与地面镜像构成偶极子形式。模拟器实验区域为围绕圆锥顶点,直径为25 m的圆形区域。具有上端馈入和下端馈入2种脉冲驱动模式,分别由两套脉冲驱动源来实现,可根据试验目的快速而便捷地切换。上端馈入脉冲源输出电压范围为50~300 kV,下端馈入脉冲源输出电压最大值可达2.95 kV。实验测试结果表明,该模拟器所产生的辐射场波形前沿可达2~3 ns,半高宽约为25 ns,波形指标符合IEC61000-2-9标准中对EMP实验波形的规定。A small vertical dipole electromagnetic pulse(EMP)simulator is developed.The antenna of the simulator has an inverted cone structure with a height of 5 m and a half cone angle of 32°.The experimental region of the simulator is a circular region of 25 m in diameter around the cone vertex.The simulator has two pulse driving modes:over-ground feed-in mode and underground feed-in mode,which are realized by two sets of pulse drivers,respectively.They can be exchanged quickly and switched conveniently according to the different applications.The output voltage range of the over-ground feed pulser is from 50 kV to 300 kV,and the maximum output voltage of the underground feed pulser can reach 2.95 kV.The experimental results show that the front edge of the radiated electric waveform generated by the simulator can be up to 2~3 ns,and the half width is about 25 ns.The characteristic of the radiated electric field waveform meets the requirements of IEC61000-2-9 standard for the EMP experimental waveform.
