Time-frequency analysis of explosion seismic effects

  title={Time-frequency analysis of explosion seismic effects},
  author={Lin Da},
By means of Fourier trans fo rm, short time Fourier transform (STFT), continuous wavelet transform (CWT) and discrete wavelet transform (DWT), an exprimental recording signal of ground moti on induced by an explosion was analyzed. The presented results show that the wav elet transform method is the best way to obtain the information details of explo sion seismic effects. In the frequency bands with high frequency values, the sei smic energy may be very small, but its peak particle vibration… CONTINUE READING
