Abstract:

Aiming at the problem that the RF front-end of millimeter-wave fuze is susceptible to interference in the complex electromagnetic environment, the front-door coupling effect of millimeter-wave fuze is studied by field-circuit combination method. The electromagnetic simulation software is used to simulate the coupling effect of the fuze antenna under the ultra-wide band high-power microwave environment, and the coupling voltage under different pulse widths and distances is numerically analyzed. The RF front-end circuit is injected by the circuit design software, and the damage mechanism of the RF front-end is analyzed by simulation data. The results show that when the irradiation field is 100 kV/m and the signal pulse width is 0.05 ns, the peak voltage of the coupled IF output signal can reach 1.8 V, which poses a serious threat to the reliability of the fuze terminal. The conclusion not only perfects the theory of high-power microwave effect of fuze, but also provides a theoretical basis for RF front -end protection.

Key words: millimeter wave fuze, ultra-wide band high-power microwave, joint simulation, front-door coupling
