The equation which defines the HEMP standard waveform was determined by fit-ting and analyzing different HEMP waveforms coming from numerical calculation . The fre-quency spectrum of standard waveform was obtained by enveloping all reasonable physical waveform spectra . According to the Hilbert transform , the standard HEMP waveform pa-rameters were carried out utilizing the signal reconstruction method based on the amplitude spectrum . In this paper , some limited physical data are presented as examples to illustrate the method in detail .
