Abstract


Informationization has become one of the main characteristics in modern warfare; a large number of electronic equipments can not be separated from modern military system. One of the biggest threaten to electronic equipments is high-intensity electromagnetic pulse radiation. The appearance of E-bombs makes the requirements of the capability against the ultra-wideband electromagnetic pulse(UWB) attack of electro-weapon and the C4I system(command, communication, control, computer and information system)command-control system higher. In that way, the technology and theory research of UWB and the protection method become more and more important in the main countries around the world.In this paper, First introduced the ultra-wideband electromagnetic pulse production, from the time domain and frequency domain analysis of ultra-wideband electromagnetic pulse waveform characteristics, the use of resonance-principles study of ultra-wideband electromagnetic pulse on the coupling efficiency of modern electronic equipment is proposed for ultra-wideband electromagnetic pulse conduction Coupled interference protection indicators. Secondly,formulas for the incident,reflected and absorbed voltage and current waves on each of the non-linear filters based on the basic equations of traveling waves and the characteristics of the non-linear filters.And the dynamic behavior of the nonlinear filters under the ultra-wideband electromagnetic pulse is analyzed.The use of PSpice software, the effect of non-linear filters suppressed the ultra-wideband electromagnetic pulses is carried out analysis and simulation. Finally,the design of the electromagnetic pulse filters is the method of combining of the transient suppression filters and the steady-state filter.The simulation model of the high frequency filters is set up and simulated and analysed the clamped voltage of the filter.
