Abstract

Numerical simulation of the solution of the (2-D, SV) inverse problem on restoration of elastic parameters (/spl lambda/,/spl mu/) and mass density (/spl rho/) of local (/spl sim//spl lambda//sub p/) inhomogeneity by the diffraction tomography method based upon the first-order Born approximation is considered. The direct problem is solved by the finite difference method. For restoration of parameters of local inhomogeneities the algebraic methods and optimizing procedures are used. In the assumption of the linear relation between desired parameters an accuracy of their restoration is estimated by the numerical simulation.
