Environmental Acoustical Modelling at Supreme Allied Commander, Atlantic, Anti-Submarine Warfare Research Center (SACLANTCEN),

Abstract

The SACLANT ASW Research Centre's programme in environmental acoustic modelling is presented, with emphasis on applications to coastal water environments. A brief description of the acoustic models in use at the Centre is given together with an inter-model study that demonstrates the consistency among the models. A sequence of examples from data/model comparisons indicates that the models can indeed describe shallow-water propagation. These studies have also demonstrated the collective role of models and data to describe coastal-water regions acoustically. Finally some results from simulation studies of propagation over a sloping bottom, seismic propagation, and the spatial distribution of surface-generated noise are presented. (Author)
