Paper Abstract

Diffraction of the acoustic fields by spatially localized inhomogeneities in oceanic waveguides is investigated by analytical methods using numerical experiments on the basis of physical modeling and by way of field measurements. The possibilities of numerical simulation and measurement under the conditions of physical modeling are discussed. It was shown that from the point of view of studying the diffraction phenomena in the ocean, the significance of these methods is due to the difficulties in performing hydroacoustic experiments. Provisional calculations and measurements under the model conditions can noticeably increase the efficiency of sophisticated field observations. Besides using the results obtained by different authors, a systematic concept of the structure of perturbed signals in the waveguides and a brief analysis of the possibility of the formulation and measurement of diffracted fields in layered waveguides are proposed.
