Coupling mechanism between radio fuzes and ultra band spectra electromagnetic pulse and enhancement of radio fuzes

Five kinds of radio fuzes are irradiated by UWS-EMP, and coupling pattern and working mechanism between radio fuzes and the energy of UWS-EMP are analysed based on irradiation experiments. Analysis results show that the energy of UWS-EMP couples to fuzes via the power module of fuzes, causes silicon control rectifier conduction, and results in fusing. The radio fuzes are enhanced based on the coupling pattern and working mechanism. The improved fuzes are irradiated and simulated. The results indicate that the enhancement has greatly improved the ability of the radio fuzes against UWS-EMP. The enhancement doesn’t influence the efficiency of the fuzes.
