摘要

针对爆破地震信号和天然地震信号的分离问题,引入基于经验周期的模态单元滤波方法,提出一种新的爆破地震信号分离算法。实验结果表明,算法可有效分离爆破地震信号和天然地震信号,为地震信号分析提供一种新的思路。
Aiming at the problem of separating exploding seismic signal from natural seismic signal,an empirical-period based mode cell filtering(EP-MCF) method is introduced.A novel EP-MCF-based method for separating the exploding seismic signal is proposed.The experimental results show that this method can separate exploding seismic signal from nature seismic signal efficiently.This paper provides a novel method for seismic signal analysis.
