Empirical mode decomposition based techniques for the estimation of experimental scholte wave dispersion
Date of Original Version
Extraction of shear wave speed in the sediment based on Scholte wave measurements is a well-established technique in ocean acoustics. One of the problems encountered while processing the Scholte wave data is the effect of higher order modes. Often it becomes hard to identify and separate out the multiple modes when they are present. This could result in incorrect estimation of phase velocities. Empirical Mode Decomposition based techniques are used in this study to explore the possibility of identifying higher order modes. Scholte wave data acquired in shallow water using a geophone array is used in this study.
