Abstract:

This is part of the Shallow-Water Autonomous Mine Sensing Initiative SWAMSI to improve the reliability of acoustic methods using a wide frequency range and scattering data not necessarily limited to monostatic signatures. The objective of this grant is to examine issues supportive of the SWAMSI team effort by improving the understanding of acoustic scattering processes relevant to MCM and the shallow water environment. The current emphasis is on the interpretation of bistatic synthetic aperture sonar images. An example of another issue investigated at Washington State University is the scattering of sound by a plastic truncated cone. The cone material and shape were selected to be relevant to high frequency signatures of certain explosive-filled mines. Other objectives involved improved understanding and modeling of scattering mechanisms that are broader in scope and are outlined below.
