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

Abstract

To understand and predict key properties of the signal intensity vector field in forward propagation with emphasis on mid-frequency, shallow water propagation. Because of enabling technologies involving MEMS and bio-inspired transduction, tomorrow s navy will depend on and utilize acoustic vector field properties (velocity, acceleration, intensity) much more than today s. Advancement in Navy relevant 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.
