| Abstract: | This paper presents in detail tomography of Rayleigh wave dispersion such as multiple filtering for measuring group velocities along mixed-path, netted dispersion inversion and structure inversion of earth interior with LSQR decomposition. The computer program frame charts are shown and numeral simulation and actual examples are illustrated. |
