Uncertainty of Propagation and Reverberation in Shallow Water Environments due to Seafloor Variability
نویسنده
چکیده
Evaluate the relative importance of various types of seafloor variability on the predictability of the temporal evolution of acoustic transmissions and reverberation in shallow water waveguides. The measures of uncertainty include the predictability of the levels of the transmissions/reverberation, the decay rates, and the coherent features of the time-depth evolution of the receptions. Seafloor variability measures include 1) the uncertainty in the background sound speed, density and attenuation of the seafloor sediments, 2) the spatial variability of these properties about the background levels, 3) the variability in the bottom bathymetry, and 4) variability in the bottom scattering strengths which cause bottom reverberation.

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...

Propagation and reverberation of acoustic fields in shallow water depend strongly on the spatial variability of seabed geoacoustic parameters, and lack of knowledge of seabed variability is often a limiting factor in acoustic modeling applications. However, direct sampling (e.g., coring) of vertical and lateral variability is expensive and laborious, and long-range inversion methods can fail to...

متن کاملModeling and Analyzing the Propagation of Uncertainty
Shallow-water environments have become increasingly important for naval operations. Unfortunately, these regions are also characterized by ocean variability and, due to typically downward-refracting conditions, an increased sensitivity to bottom properties. Of course, bottom properties are also often poorly known, especially in shallow water. As a result, there is a lot of concern about 1) how ...
