Environmental Acoustics and Intensity Vector Acoustics with Emphasis on Shallow Water Effects and the Sea Surface

Abstract

The long-term goal is to understand and predict key properties of the signal intensity vector field as it propagates away from an active sound source, with emphasis is on mid-frequency, shallow water propagation. New and enabling technologies such as MEMS and bio-inspired transduction, will allow tomorrow s Navy to exploit acoustic vector field properties (velocity, acceleration, intensity) much more than today s. Furthermore, advancement of current Navy capabilities will be in part realized through a better understanding of the environmental and acquisition geometry dependence (source depth, range, etc.) of the vector field in a shallow water environment.
