Shallow Water Waveguide Influences on Time Reversing Array Retrofocusing

Abstract

This project seeks to quantitatively predict time-reversing array retrofocus size and longevity in the presence of the physical phenomena common in shallow ocean waters. These phenomena include guided-wave propagations, acoustic absorption, dynamic internal waves, and bottom roughness. In addition the influence of the orientation of linear arrays with respect to the waveguide axis and the source has been addressed.
