Radiation effects of ultra-wide spectrum on radio fuze and its protection

This paper discusses the ultra-wide spectrum high power microwave(UWS-HPM) radiation effects, coupling approach, action mechanism and protection methods of specified radio fuze. Radiation experiment has been done on multi-pose fuze using UWS-HPM generator. The experiment indicates that radiation effects are the strongest when the axis of projectile are parallel to the E-field polarization direction of the UWS-HPM. Theoretical analysis and radiation test reveal the coupling mechanism of UWS-HPM energy: the pulse current coupled by the fuze and projectile transmits to fuze executive-circuit through power-supply-circuit of the fuze, rising rate of the pulse current exceeds the dV/dt(critical rate of rise of off-state voltage) of SCR(silicon control rectifier). Adding protection component to e
