Wave-Driven Marine Boundary Layers: Implications for Atmospheric Electromagnetics and Ocean Acoustics

Abstract

The long-term goal of this effort is to advance our quantitative understanding of the factors affecting signal propagation in the marine environment, essential for radio tracking, communication and guidance applications. A significant issue in this scientific area is the reproducible tendency of models for propagation to overestimate the signal's intensity at the receiver (Barrios and Patterson (2002)). Currently employed algorithms rely on the return signal's intensity for determining the distance to an object, thus a signal misinterpretation has a potentially far-going practical consequences. The situation suggests that physical mechanisms or experimental circumstances responsible for signal degradation, contraction of the coherence radius, etc., are not fully understood and accounted for.
