Study on the equivalent pulse current injection waveform of SGEMP

摘要:

采用电磁范数对系统电磁脉冲(SGEMP)脉冲电流注入(PCI)波形参数的确定方法进行研究。负载分别为高阻和低阻时，对SGEMP敏感端口响应典型波形进行电磁范数参数化表征，综合考虑等效波形的上升时间、峰值、携带的能量和电荷量与响应波形的差异情况，开展了PCI等效波形参数研究。仿真结果表明，方波等效波形可以很好地模拟出响应波形，等效波形与响应波形的峰值一致，频谱特征近似；等效波形的上升时间、携带的能量和电荷量等参数通过调整脉宽即可实现与响应波形一致。因此，可采用电磁范数对SGEMP响应波形进行参数化表征等效，获得的等效波形容易在实验室生成，从而为采用电流注入方法开展SGEMP研究提供一种新的途径。

Abstract:

The determination method of Pulse Current Injection(PCI) waveform parameters of System Generated Electromagnetic Pulse(SGEMP) is studied by using electromagnetic norm. When the load is high and low resistance respectively, the typical response waveform of SGEMP is double exponential waveform and Gaussian waveform. Considering the difference between the rise time, the peak value, the energy and the charge carried by the equivalent waveform and the response waveform, the equivalent waveform parameters of pulse current injection are studied. The results show that the square wave equivalent waveform can simulate the response waveform according to the characteristics of the response waveform and electronic system. Therefore, it is possible to use electromagnetic norm to parameterize the equivalence of SGEMP response waveform, and the equivalent waveform can be easily generated in laboratory, which provides a new way for the study of SGEMP by the current injection method.
