Improvised explosive devices(IEDs)have been widely used in terrorist attacks in recent years,and strong electromagnetic pulses are an effective means of countering IEDs.In this paper,irradiation simulation tests on a remote-controlled IED are conducted using two types of electromagnetic pulses,namely wide-band high-power microwave(WBHPM)and narrow-band high-power microwave(NBHPM)to study IED cable coupling effects of e-lectromagnetic pulses.The simulation results show that the peak cable coupling voltage of IEDs is greatly affected by the irradiation angle of the electromagnetic pulses,with the maximum value differing from the minimum value by nearly two orders of magnitude.Variations in cable length can cause peaks in the cable coupling peak voltage,and the cable length corresponding to the peak increases as the frequency of the electromagnetic pulse decreases.The coupling peak voltage is proportional to the electromagnetic pulse peak,but the pulse width and rise time of the NBHPM only change the waveform of the coupled signals.This paper analyzes the coupling effects of WBHPM and NBHPM on IED cables,providing reference for the selection of electromagnetic pulse sources for counter-IED pur-poses.
