摘要
针对窄带高功率微波(narrowband high power microwave,NHPM)辐照下线缆面临干扰的问题。基于CST仿真软件,建立了线缆仿真模型,模拟了NHPM辐照下裸露线缆的耦合响应特性。仿真计算了不同中心频率、不同脉冲宽度的4种NHPM对不同长度裸露线缆耦合特性的影响,及不同线缆长度对耦合特性的影响。仿真结果表明:裸线缆耦合电压峰值随裸线缆长度的增加而增加,最终稳定在一个区间内;裸线缆长度为一些特定值时,会出现耦合电压波形失真的现象。本研究为线缆的防护设计提供了依据,也为其他线缆耦合仿真实验提供参考。
A cable without shielding layer under narrowband high power microwave(NHPM)irradiation is simulated by using computer simulation technology(CST)software,and the changes of port voltage in exposed cable under microwave irradiation are analyzed.The simulation experiment calculates the coupling characteristics of four types of narrowband high power microwaves with different center frequencies and pulse widths on exposed cables with different lengths.The simulation result shows that as the length of the cable increases,the peak coupling voltage of the cable increases and finally stabilizes within a certain range.The waveform of the coupling voltage will be distorted when the cable lengths reach certain specific values.The study provides a basis for the cable protection design and also provides a reference for other cable coupling simulation experiments.
