The results of theoretic calculating and real data processing confirm that the reconstructed trace by this method fits the wave shape, amplitude and phase of raw data.
The noise-extracted signal which is reconstructed by the revised wavelet coefficient could clearly reflect the time difference between incidence wave and reflection wave.
