Abstract
The paper discusses the method of multichannel analysis of surface waves. We propose an automated method of surface waves extraction, based on the time-frequency representation of seismograms and their subsequent spatial spectral analysis. This approach is robust for the extraction of smooth and realistic dispersion curves in automatic mode. This provides a more reliable assessment of high-velocity sections of shear waves by the method of multichannel analysis of surface waves. The article presents the results of testing of the developed approach with using noisy synthetic and real seismic data.
