关 键 词：seismic waves geophysical signal processing spectral analysis Gaussian noise high-order spectral analysis micro-seismic signal bispectrum analytic method white/colored Gaussian noise power spectrum analysis feature extraction
摘 要：正In this correspondence,on the basis of introduction of bispectrum analytic method,it is theoretically proved that this method can effectively eliminate white/colored Gaussian *** validate this,the micro-seismic signal resulting from wheeled and tracked vehicles is analyzed using *** result of comparison with power spectrum analysis shows that bispectrum analysis is superior to power spectrum analysis in feature extraction, which agrees very well with the analytic result.
