Abstract

In this paper, we combine the matched-field method with the boundary integral equation method from inverse scattering theory to study a sound source localization problem in a shallow ocean with an unknown large inclusion. We assume that there is an unknown inclusion embedded in a shallow water waveguide. To localize a continuous wave (CW) source, we send in a number of 'mode waves', which scatter off the unidentified inclusion and are received by a hydrophone array. Combining the information of these scattered waves and the signal from the point source, we present an algorithm to estimate the location of the CW source. A numerical simulation using this method is presented.
