根据国际电工委员会(IEC)制定的最新高空核电磁脉冲(HEMP)标准,对辐射波模拟器关键结构的指标参数进行分解。分析了不同模拟器激励源和双锥结构对辐射电场波形关键参数的影响,基于分析曲线提出脉冲源的指标,最后给出辐射波HEMP模拟器自由空间辐射电场的计算波形。论文结果对此类模拟器的设计具有重要参考价值。

According to the new standards on the high-altitude electromagnetic pulse （HEMP） developed by International Electrotechnical Commission （IEC）, the target parameter requirements of the key structure of the hybrid HEMP simulator are decomposed. Firstly, the influences of the different excitation sources and biconieal structures to the key parameters of the radiated electric field waveshape are investigated and analyzed. Then based on the influence curves the target parameter requirements of the pulse generator are proposed. Finally the appropriate parameters of the biconical structure and the excitation sources are chosen, and the computational result of the electric field in free space is presented. The results are of great value for the design of the hybrid HEMP simulator.
