为了得到聚能爆炸期间真实的电磁脉冲,通过对不同状态下记录的背景信号进行分析,得到了聚能爆炸过程中背景信号的特征,应用小波变换对失真的瞬态电磁脉冲进行处理,实现了噪声的滤除及干扰信号的分离,进而提取到了真实的聚能爆炸电磁脉冲,在此基础上,计算得到了聚能爆炸电磁辐射的频谱分布。结果表明,聚能爆炸引起的电磁辐射频率主要分布在2MHz以下。
In order to obtain the real electromagnetic pulse during the cluster explosion, the background signal recorded in different states was analyzed, the characteristics of the background signal during the process of energy accumulation and explosion were obtained, and the transient electromagnetic pulse with distortion was processed by wavelet transform. Noise filtering and interference signal separation, and then extract the real polyblend explosive electromagnetic pulse, on this basis, calculated the spectrum distribution of the polyblend explosive electromagnetic radiation. The results show that the frequency of electromagnetic radiation caused by the energy dispersive explosion is mainly distributed below 2MHz.
