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 undersea surveillance systems of the US Navy for both" passive and active detection, localization, imaging and monitoring. Here OAWRS refers to all applications of acoustic remote sensing in an ocean waveguide. The long term goal of the proposed research is to advance the state of the art of both passive and active undersea surveillance by helping to establish the fundamental Principles governing acoustic propagation, scattering, noise, clutter, reverberation and fluctuation in an ocean waveguide and then utilizing this knowledge to develop optimal undersea surveillance systems 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 lead to new approaches in undersea remote sensing. The primary objective of this proposal is to continue the data analysis and model development initiated in a series of major ocean acoustics experiments the PI has conducted and conduct major new ocean acoustics experiments in theJapanese Maritime Zone and the Nordic Seas. These unique and difficult experiments provide dat"a sets that will enable significant advances in every aspect of undersea remote sensing with ocean waveguide acoustics.
