Determining the Structure of a Three-Dimensional Medium According to Data on the Travel Times of Internal Wave Sources

The basic principles of the reverse wave approach are presented. A new algorithm for processing experimental data is developed. Several test models of an inhomogeneous three-dimensional medium are proposed. The new algorithm is tested with synthetic input data determined in the ray approximation for test models. The results from determining the structure of the Earth’s crust are presented using the Azerbaijan region as an example.
