Remote Sensing in Fluctuating Range-Dependent Littoral Environments with Clutter

Abstract

The long-term goal is to understand and characterize acoustic clutter and background reverberation in long range sonars operating in range-dependent continental shelf environments. Develop operational and signal processing techniques to distinguish biological or geological clutter from scattered returns due to man-man targets. In the second area, the dominant causes of fluctuation in measured acoustic signals is examined and used to determine the extent to which environmental variabilities limit our ability to perform source localization and environmental parameter estimation through match-field processing and beamforming in fluctuating ocean waveguides.
