Source localization in a shallow-water channel with a rough surface

The problem of source localization in a shallow-water sea is considered, in which the fully developed sea is the prevailing sound-scattering mechanism. Using the criterion of the signal-to-noise-ratio maximum, we construct robust algorithms for estimating the parameters of partially coherent signals. The results of testing these methods for solving the inverse problem using experimental data obtained on a stationary path in the Barents Sea are presented. It is shown that under real conditions, the corresponding algorithms are serviceable and provide satisfactory quality of reconstructing a source located at a distance of ∼15 km from an antenna array.
