【摘要】 针对地震次声波信号次声波干扰严重,有价值的次声波信号埋没在复杂的噪音背景之中而难以分析的情况,采用将自适应滤波应用于次声波信号的处理,并将传统方法进行简单的改进。通过实际地震数据的去噪处理,将自适应滤波处理的信号与原信号进行对比的试验,得出自适应滤波完全可以完美的应用于地震次声波数据处理的结论,并使地震监测系统更加完美。更多还原

【Abstract】 According to the seismic signal infrasonic wave interference, signal buried valuable and difficult to analyze in complex noise background conditions, the adaptive filtering is applied to the treatment of signal, and the traditional method is simple. Through the actual seismic data denoising, contrast tests were carried out with the original signal adaptive filtering,the adaptive filter can be perfect in the earthquake infrasound data processing results, and make the earthquake monitoring system more perfect.更多还原
