Abstract
The authors propose a new approach to processing multichannel data on surface waves to enhance interference immunity of dispersion curves of the Rayleigh wave phase velocities determined from the analysis of motion paths of particles in the time-and-frequency domains based on the S-transform applied to the two-component seismic records. Efficiency of the approach is demonstrated as a case-study of processing of the synthetic and field data of shallow seismic investigations.
