摘要 利用希尔伯特-黄变换(HHT)中经典模态分解(EMD)法,对浅层地下爆炸场采集的震动信号进行分解,得到满足一定条件的IMF分量,再对其进行希尔伯特变换,得到能量谱图,通过对波形和能量谱图的分析,实现对浅层爆炸场信号的分析及特征提取。 By making use of Empirical Mode Decomposition(EMD) method in Hilbert-Huang Transform, the acquired vibration signals of shallow underground explosion field are decomposed and IMF components meeting certain conditions are obtained to which Hilbert Transform is done and energy spectra are yield. By analyzing the waveforms and spectra, the analyses and extraction of the signals of shallow explosion field are completed .
