摘要
为了研究火箭弹的电磁脉冲效应,设计以方波脉冲产生的辐射场为激励源、火箭弹的电火工品为对象的电磁辐照实验,采用系统辨识方法对该系统的脉冲能量耦合通道进行建模.实验结果表明,所建模型能够较好地预测出响应波形.仿真结果证实系统辨识对火箭弹电磁响应预测的正确性,为火箭弹的电磁效应评估提供一种有效的仿真方法.
In order to study the electromagnetic pulse effects of rockets, the pulse irradiation experiment of electro-explosive devices is designed with square wave pulse as drive sources.The pulse energy coupling transfer function of rocket system is modeled based on system identification.As a result, the model can predict the response wave shapes well. The simulation result proves that the effective application of system identification in electromagnetic pulse response prediction of the rocket. It offers an effective simulating method for evaluation of the electromagnetic effect.
