Accuracy and resolution of the travel-time tomography

Summary

The geological medium is assumed to be a representation of a random medium described in terms of the first two statistical moments: the mean value and the medium correlation function. The proposed approach to the seismic travel-time tomography enables to derive the equations for the inversion of travel times without additional subjective a~priori information, and to estimate the accuracy and resolution of the resulting seismic model of a geological structure.

Keywords
