Computational kinematic diagnostics of the probing signal speed using a priori information about the medium under study

A computational technology for kinematic diagnostics of the velocity distribution of a sounding signal in seism acoustic media is presented under the conditions of linearization of the emerging inverse kinematic problem. The problem statement, construction of a solution and a computational algorithm based on the CT method are presented. The use of CT is ensured by the organization of a tomographic observation system (location of sources and receivers of the probing signal on a circle). Linearization is performed near the linear depth function (variable Z of the X Y Z space), identified in the desired velocity function and assumed to be known. The main attention is paid to the organization of this component, which significantly affects the accuracy and reliability of the resulting solution. The results of computer experiments illustrating the solution of the problem under consideration are presented. Contribution of the authors: the authors contributed equally to this article.
