引信-超宽带强电磁脉冲效应阈值试验研究

In order to clarify the interference and damage effects of ultra-wideband electromagnetic pulse on fuze, the threshold interval of fuze-electromagnetic pulse coupling effect is determined. It is difficult to accurately assess the anti-interference ability of fuze in the electromagnetic pulse environment because the fuze-electromagnetic pulse effect data samples are few. To solve this problem, in this paper, a threshold analysis model of fuze-electromagnetic pulse coupling effect is established based on Markov-Monte Carlo estimation. The fuze effect test system is constructed by a typical ultra-wideband electromagnetic pulse simulator. The fuze-electromagnetic pulse effect law and interference threshold are obtained, through the electromagnetic pulse irradiation test of the typical fuze. The test results show that the mean value of the fuze communication failure threshold is 28.262 kV/m, and the 95% confidence interval is (27.390, 29.129) kV/m; the posterior expectation of variance is 1.867 kV/m, and the 95% confidence interval is (0.834, 4.182) kV/m. This method can be used to estimate the electromagnetic pulse effect threshold for various fuzes, and provide the theoretical foundation and test means for improving the fuze's ability of anti-electromagnetic interference.
