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 perturbations affecting the probing sound held. The other approach is based on the Obukhov quasipotential equation. A procedure is proposed for the reconstruction of the vector of a two-dimensional current from the projections of its Fourier transform with the use of the Rytov approximation. The mode representation of acoustic fields in a moving medium is considered.
