On the one problem of wave diagnostic

This work is devoted to the development of methods and algorithms of the solution of a nonlinear three-dimensional inverse problem of wave diagnostics of heterogeneities in homogeneous environments in approximation of Helmholtz equation. By virtue of computational complexity of the problem, its solution is possible only with use of a supercomputer. The problem consists in seeking the unknown factor in the equation with partial derivatives. The problem is transformed to a system of operator equations with respect to an unknown factor and a wave field. Effective algorithms of its solution with the use of supercomputers having a parallel architecture as a result.
