A Unified Approach to Passive and Active Ocean Acoustic Waveguide Remote Sensing
Abstract
Ocean acoustic waveguide remote sensing (OAWRS) is the basis for the primary underseasurveillance systems of the US Navy for both passive and active detection, localization, imagingand monitoring. Here OAWRS refers to all applications of acoustic remote sensing in an oceanwaveguide. The long term goal of the proposed research is to advance the state of the art of bothpassive and active undersea surveillance by helping to establish the fundamental principlesgoverning acoustic propagation, scattering, noise, clutter, reverberation and fluctuation in anocean waveguide and then utilizing this knowledge to develop optimal undersea surveillancesystems that take full advantage of inherent opportunities in waveguide physics and statistics.This goal has been given a very focused direction by a series of experiments conducted by the PIwhich have had significant national and international impact and have led to and continue to leadto new approaches in undersea remote sensing. The primary objective of this proposal is tocontinue the data analysis and model development initiated in a series of major ocean acousticsexperiments the PI has conducted and conduct a major new ocean acoustics experiment in theNordic Seas in 2018. These unique and difficult experiments provide data sets that will enablesignificant advances in every aspect of undersea remote sensing with ocean waveguide acoustics.
