摘要：
Aiming at the problem that frequency modulation continuous wave (FMCW) fuze is susceptible to interference in the ultra-wideband electromagnetic pulse environment, the method of field-circuit joint simulation is applied to studing the coupling effect of ultra-wideband electromagnetic pulse in the radio frequency (RF) front end of fuze. The simulation experiment adopts the method of first irradiation and then injection. Firstly, the fuze RF front-end model is irradiated by plane wave, and then the coupling voltage is introduced into the fuze receiver for effect analysis. The experimental results show that ultra-wideband electromagnetic pulse can hardly damage the internal components of the receiver, and its coupling effect is mainly reflected in the interference effect. When the energy of coupling into the intermediate frequency band of the receiver is enough to submerge the normal output signal energy, the fuze ranging function will be disturbed. © 2020, Editorial Office of Systems Engineering and Electronics.
