Shallow Water Propagation and Surface Reverberation Modeling

نویسنده

  • Grant B. Deane
چکیده

The primary long-term goal is to measure and model high-frequency acoustic propagation in the presence of surface gravity waves and breaking waves to better understand the effects of surface reverberation on shallow water, underwater acoustic communications (ACOMS). Secondary long-term goals are to exploit measurements of breaking wave noise to infer bubble cloud populations at the sea surface and their effect on reverberation, and to model high-frequency, forward scattering from sea ice.

Perturbation Modeling and Data Analysis in ASIAEX

Shallow water acoustics and the performance of sonar systems in littoral environments are critical areas of interest to the US Navy. In response to this, the Office of Naval Research sponsored a series of acoustics experiments in the East and South China Seas, hereafter referred to as ASIAEX. Components of these experiments included studies of shallow water reverberation, geoacoustic properties...

Transport Theory for Propagation and Reverberation

Previously, our shallow water propagation model based on transport theory was extended to include reverberation, and it was found that sea surface forward scattering could have very important effects on reverberation level at mid frequencies, e.g., at 3 kHz. One objective in FY13 was to obtain reverberation measurements during TREX13 that can be used for a definitive verification of these impor...

Finite element modeling of reverberation and transmission loss in shallow water waveguides with rough boundaries.

A finite element model for the reverberation and propagation in a shallow water waveguide with a sandy bottom was calculated for five different environments at a center frequency of 250 Hz. The various environments included a rough water/sediment interface, a rough air/water interface, roughness at both interfaces and downward and upward refracting sound speed profiles with roughness at both in...

Modeling of Mid-Frequency Reverberation in Very Shallow Water

A specific objective of this research is to develop a mid-frequency shallow-water reverberation model relevant to specific conditions (1 – 10 kHz, ~20 m water depth, ~ 5 km range) of the ONR Target and Reverberation experiment [1] performed during the spring of 2013 (TREX13). The research is to result in developing computer simulation codes and algorithms for the TREX13 acoustic data analysis b...
