Separate reconstruction of the speed of sound, density of the medium, and coefficient of absorption in tomographic problems

Аннотация

A procedure is proposed for separating contributions to the scatterer function by inhomogeneities of the speed of sound, density of a medium, and coefficient of absorption. The scatterer function is reconstructed by solving the inverse problem. The power index of the absorption coefficient’s frequency dependence is determined simultaneously. The resistance to interference of this procedure is investigated by simulations in the multifrequency mode.
