Abstract:

Acoustic clutter is the primary problem encountered by active sonar systems operating in Continental Shelf environments. Clutter is defined as any returns from the environment that stand prominently above the diffuse and temporally decaying reverberation background and so can be confused with or camouflage returns from an intended target such as an underwater vehicle. The long-term goal of this program is to determine and understand the physical mechanisms that cause acoustic clutter in continental shelf environments with little or no bathymetric relief and to use this knowledge to develop predictive tools to enhance the detection, localization and classification of underwater targets.
