ABSTRACT. Underwater source localization based on acoustic modeling has been a subject of intensive research since a long time. In the case of shallow water scenarios (which are characterized by multilayered bottoms) normal-mode based acoustic propagation models are often combined with Matched-Field Processing techniques in order to provide accurate estimates of both source range and depth...Keywords: underwater acoustic modeling, ray-based models, normal mode models. RESUMO. A localização de fontes submarinas por meio de modelos de propagação acústica é um antigo problema de grande interesse científico. Em cenários deáguas rasas, que se caracterizam normalmente por fundos com complexos sistemas multicamadas, os modelos de propagação baseados na teoria de modos normais são geralmente combinados com técnicas de Processamento por Campo Casado para...Palavras-chave: modelagem ac´ustica submarina, modelos de raios, modelos de modos normais.
