In addition to the earlier answer, I would only add the governing equations relating surface wave phase velocity to shear-wave velocity can be found in many seismology textbooks.
good luck in your search!
Almost all the energy that propagates in the subsurface as a result of an energization occurs through surface waves (mainly Rayleigh waves). The analysis of Rayleigh waves using MASW technique is performed through the treatment of the spectral seismogram, that is a result of a double Fourier transform, which returns the signal spectrum. In this domain (transformed domain), it is simple to go to separate the signal relative to the Rayleigh waves from other types of signal.
Hello,
May be you should try SFK transform for MASW.
The SFK transform is the enhanced method for f-k analysis of MASW data.
See the matlab code with the SFK transform implementation (dispersion curves are plotted): Code SFK-transform
it is very easy. You run an example: it draws the dispersion curves - you see how it works.
also you can get it on mathworks:

Best Regards!
