Shallow-Water Acoustics
shallowand deep-water acoustics. But during the cold war, the research emphasis shifted abruptly to deep water, where the ballistic missile submarine threat lurked (see box 1). After the cold war, the onset of regional conflicts in coastal countries shifted the focus again to shallow water. Those waters encompass about 5% of the world’s oceans on the continental shelves, roughly the region from...
متن کاملThree - Dimensional Shallow Water Acoustics
Both physical oceanographic processes and marine geological features in the continental shelf can cause the medium properties to have lateral heterogeneity, so horizontal refraction of sound can occur and produce significant three-dimensional (3-D) sound propagation effects. The long-term goals of this project are targeted on understanding the 3-D acoustic effects caused by the environmental fa...
متن کامل15: Shallow-Water Mud Acoustics
Goals include the development of models and methods that explain observed material and acoustic properties of different physical types of shallow-ocean mud sediments. Other goals are to assess prior data relating to the acoustic properties of mud and to provide guidance in the development and interpretation of experiments. A related goal is to construct models that will guide inversion techniqu...
متن کاملAcoustical Oceanography and Shallow Water Acoustics
In this paper, we review some recent new results in shallow, coastal waters from both ocean acoustics (the study of how sound propagates and scatters in the ocean) and acoustical oceanography (the study of ocean processes using acoustics as a tool).
متن کاملMulti-static Active Acoustics in Shallow Water
The objective of the ocean acoustics components of the GOATS project is to develop a fundamental understanding of the 3D acoustic environment associated with the mine countermeasures (MCM) problem in shallow water (SW) and very shallow water (VSW) and to develop efficient physics based propagation and scattering models incorporating aspect-dependent targets and seabed features, and the waveguid...
