采用经验周期模态单元滤波方法分离爆破地震信号和天然地震信号

Separation of Exploding Seismic Signal from Natural Seismic Signal by Empirical Period Based on Mode Cell Filtering Method

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.
