针对消除地震信号中的汽车震动干扰问题,引入基于经验周期的模态单元滤波模型,提出一种基于经验周期模态单元滤波算法消除地震波中的汽车震动干扰的新方法,并设计天然地震波信号的消噪试验。实验结果表明,新方法比传统的Butterworth方法更好,为地震信号中汽车震动干扰消除提供一种新的思路。 Aiming at the problem of eliminating the vibration of vehicle in the seismic signal, a modal unit filtering model based on empirical cycle is introduced, a new method based on the empirical periodic modal unit filtering algorithm to eliminate the vibration of the vehicle in the seismic wave is proposed and the natural seismic signal Noise test. The experimental results show that the new method is better than the traditional Butterworth method and provides a new idea for the elimination of vehicle vibration in seismic signals.
