Restoration of elastic and velocity parameters in diffractiontomography

摘要

Numerical simulation of the solution of the (2-D, SV) inverseproblem on restoration of elastic parameters (λ,μ) and massdensity (ρ) of local (~λ_p) inhomogeneity by thediffraction tomography method based upon the first-order Bornapproximation is considered. The direct problem is solved by the finitedifference method. For restoration of parameters of localinhomogeneities the algebraic methods and optimizing procedures areused. In the assumption of the linear relation between desiredparameters an accuracy of their restoration is estimated by thenumerical simulation
