Acoustic Scattering Processes for Target Discrimination

Abstract

The objective of this project is to improve the understanding of the acoustical scattering of objects near interfaces and related approaches for identifying signal features related to target responses. This project extends research examining the properties of scattering by targets at (or breaking through) a free surface at the top of a tank of water or partially buried in sand and targets illuminated by evanescent waves in fluids or by acoustic beams. The proposed research also examines selected aspects of target responses to acoustic radiation forces. Aspects of the research will involve the laboratory-based application and/or testing of acoustical imaging methods. This research should aid the understanding of how surfaces adjacent to targets alters their acoustical images and responses and help in the development of methods for discriminating between natural acoustic clutter and man-made objects of interest. Thus the research is relevant to improving the use of acoustic scattering for object identification and improving naval capabilities.
