| 摘 要： | 针对应用广泛的单极天线，基于矩量法分析了天线对高空电磁脉冲和高功率微波、超宽带非核电磁脉冲的响应，计算了三类电磁脉冲通过天线耦合产生感应电流频谱响应和时域瞬态响应，窄带脉冲的响应曲线与入射脉冲有较大相似性，电流响应峰值依次为100，60和10.3 A，对现有大功率限幅器的功率容限提出了更高的要求。

| Abstract: | Based on the widely used monopole on conducting plane,the response characters of antenna exposed to high electromagnetic pulse,high power microwave and ultra wideband electromagnetic pulse were analysed by moment method,and the time domain and frequency domain response waveforms of the three types electromagnetic pulse coupled to the antenna was calculated.The monopole response waveform of the narrowband pulse is much similar to the incident waveform,the peak current is 100 A,60 A and 10.3 A ordinally,boosting the demand for higher power capacity of the actual high power limiters. |
