Acoustic Scattering Models and Experiments
Abstract
Approved for Public ReleaseThe objective of this project is to improve methods for acquiring acoustical signatures of targets in wat,er and models for understanding such signatures and methods of extracting, displaying, and using signatures. One of the approaches i,n the proposed research concerns measuring, modeling, and displaying elastic aspects of target responses in the mid-to-high frequenc,y sonar region. Another approach concerns exciting, measuring, and improved understanding responses associated with low-frequency mo,des. Methods of selective low-frequency mode excitation could involve electromagnetic stresses and ultrasonic radiation forces of f,ocused sound beams. This component involves laboratory experiments and models to improve the understanding of mode energy dissipatio,n and mode excitation. This research should aid in discriminating between natural acoustic clutter and man-made objects of interest., Multi-function sonar configurations may be used including the special caseof vortex-beam sonars. Thus, the research is relevant to,improving the use of acoustic scattering for object identification and improving naval capabilities.
