| 摘 要： | 针对限幅器在高功率微波(HPM)作用下的尖峰泄漏问题,基于搭建的HPM注入实验平台和电路仿真开展了研究。研究结果表明:当注入功率超过6 dBm时,限幅器会出现尖峰泄漏现象,限幅器泄漏尖峰的上升沿与脉宽随着注入功率的增加而减小,而绝对尖峰泄漏功率随注入功率的增加呈增长趋势,平顶泄漏功率呈近似"线性增加-缓慢下降-小幅增长"趋势。并且,实验结果显示:HPM脉宽与重频对限幅器尖峰泄漏特性基本无影响,其泄漏特性变化规律与单次脉冲的基本一致;尖峰泄漏能量随注入功率的增加而降低。

| Abstract: | In this work, the response characteristics of the microwave limiter under various high power microwave irradiation are investigated via both simulation and experiment, and the simulation results match those of the experiment well. When the input power exceeds 6 dBm, a spike leakage phenomenon is observed. As the input power increases, the rise time and pulse width of the leakage peak decrease, whereas the leakage power gradually increases. However, the leakage power of the plateau firstly linearly increases, then gradually decreases, and finally slightly increases. Moreover, the pulse width and repetition frequency have almost no influence on the characteristics of leakage pulse, and the leakage energy decreases as the injection power increases. |
