Programs to calculate synthetic Fourier-Bessel expansion coefficients for a given model of subsurface structure and to calculate synthetic waveform data for a given set of Fourier-Bessel expansion coefficients.
Repository location:: src/green/synt
These programs are used in the context of the inversion of shallow seismic wavefields. The repository contains software for a two-stage approach.
- Modified Fourier-Bessel transformation for shallow seismic data
- Inversion of Fourier Bessel expansion coeffcients
The following programs are provided:
dig.f: A program to produce artificial coefficients in the file format of Fourier-Bessel expansion coefficients which are derived from a set of dispersion curves. This is used to enter the second stage of inversion from a set of dispersion curves without a wavefield transformation of actual waveform data.
syg.f: Calculates synthetic Fourier-Bessel expansion coefficients with the reflectivity method.
rhesyg.f: Calculates synthetic Fourier-Bessel expansion coefficients with the reflectivity method. This version uses the physically correct rheology of a standard-linear-solid.
