Paper Title:
Application of Wavelet Transform Theory to Rayleigh Wave Exploration
  Abstract

Based on researches on conventional analytical method of the Rayleigh wave testing data, the wavelet theory is introduced to analyze the data and we find that wavelet components of the Rayleigh wave testing data on the scale of 2-1 and 2-2 are high frequency interference, so we omit them. Afterwards, the coherent analysis, phase-different analysis and power spectrum analysis of the smoothing signal on the scale of 2-2 are made to obtain the frequency dispersion curve, which is smoother and more reasonable than that obtained without using wavelet denoising. Besides, the testing data of shear wave is closer to the calculated value. The results indicate that applying wavelet analysis to the disposal of the Rayleigh wave testing data works efficiently.
