Abstract

Abstract: The field-circuit joint simulation test of the fuze RF front-end was made for the front-gate coupling of fuze under high-power microwave irradiation. A RF front-end model of fuze is established by simulation software, and the coupling effect of front-gate of fuze is analyzed by the test method of irradiation before injection. The test results show that the sensing elements of RF front-end of fuze are easy to be damaged by high-power microwave. The damage effect of high-power microwave is more obvious when the rise time of pulse signal is short; and when the distance between HPM source and fuze is long, the normal ranging function of fuze will be disturbed, but the interference effect caused by the change of flat top width of pulse signal is not obvious.
