INVERSE SCATTERING PROBLEMS IN THE ACOUSTICS OF MOVING-MEDIA

Reconstruction of the velocity distribution in an oceanic current from tomographic experimental data is considered. One approach is based on separating the velocity-related effects from the linearized acoustic equations of hydrodynamics and considering these effects as perturbati ons affecting the probing sound held. The other approach is based on t he Obukhov quasipotential equation. A procedure is proposed for the re construction of the vector of a two-dimensional current from the proje ctions of its Fourier transform with the use of the Rytov approximatio n. The mode representation of acoustic fields in a moving medium is co nsidered.
