Developing the methods and algorithms for solution of inverse acoustical scattering problems

The results of experimental studies of the nature of the propagation of acoustic signals in shallow water are presented, including the case of an ice layer presence. The results of the reconstructing the waveguide parameters and estimating the mode structure of the acoustic field by experimental data in the shelf zone are presented. The possibilities of functional algorithm that is intended for the purposes of tomography of acoustic scatterers represented by refractive-absorbing inhomogeneities and, simultaneously, by a vector field of currents are numerically investigated.
