摘要

摘要: 针对高功率微波对毫米波引信的前门耦合效应问题，利用电磁仿真软件对某型毫米波调频连续波引信模型进行辐照试验，并与引信前端限幅电路结合进行联合仿真。在此基础上，继续设计正交试验，对信号参数影响水平进行分析。通过仿真试验发现，在高功率微波信号频率和引信工作频率对准的情况下，辐照场强峰值为60 kV/m时，天线末端耦合电压最大可达188 V；当辐照场强峰值为40 kV/m时，改变辐照信号特征参数，发现长脉宽信号更容易导致限幅器的热击穿效应；信号上升时间会影响天线末端耦合电压波形复杂程度，当信号峰值、脉宽一定时，上升时间为5 ns的输入信号导致的尖峰泄漏电压约为5.94 V，而当上升时间为0.1 ns时，尖峰泄漏电压为18.4 V，并且限幅电路更快达到饱和状态；通过正交试验发现，信号上升时间对尖峰泄漏峰值电压的影响最大，信号峰值对其的影响次之。

Abstract: Aiming at the front door coupling effect of high-power microwave on millimeter wave fuze, the electromagnetic simulation software was used to irradiate a certain millimeter wave FM continuous wave fuze model, and the joint simulation was carried out with the front-end limiting circuit of the fuze. On this basis, orthogonal experiments are designed to analyze the influence level of signal parameters. When the high-power microwave signal frequency is aligned with the fuze working frequency, the simulation results show that the maximum coupling voltage at the end of the antenna can reach 188 V when the peak radiation field intensity is 60 kV/m. When the peak radiation field intensity is 40 kV/m, changing the characteristic parameters of the radiation signal and finds that the long pulse width signal is more likely to cause the thermal breakdown effect of the limiter; the rising time of the signal will affect the end of the antenna. When the peak value and pulse width of the coupled voltage waveform are fixed, the spike leakage voltage caused by the input signal with rise time of 5 ns is about 5.94 V, while the spike leakage voltage is 18.4 V when rise time is 0.1 ns, and the limiting circuit reaches saturation state faster. The orthogonal experiment shows that the spike leakage peak voltage is most affected by the rise time of the signal, and the signal peak is the largest, meanwhile the value has the second effect on it.
