摘要
阐述对不同标准的NEMP波形时域波形进行频谱分析,得出脉冲波形的时域上身沿时间和半高宽度时间越短,其频谱带宽越宽,主要频段范围越广.并分析在10MHz下的空间场分布,结果表明,随着核电磁脉冲波形上升沿越来越陡峭,核电磁脉冲的电场值先逐渐增大,随后减小.因此,对于空间电场分布,核电磁脉冲波形不是越陡峭越好,而是存在一个最大值.
Abstract
This paper describes the spectral analysis of time-domain waveforms of different standard NEMP waveforms,and concludes that the shorter the time-domain upper body time and half width time of pulse waveforms,the wider their spectral bandwidth,and the wider the main frequency band range.It analyzes the spatial field distribution at 10MHz,and the results show that as the rising edge of the nuclear electromagnetic pulse waveform becomes steeper,the electric field value of the nuclear electromagnetic pulse first gradually increases and then decreases.Therefore,for the spatial electric field distribution,the waveform of nuclear electromagnetic pulses is not necessarily steeper but has a maximum value.
