Acoustic Scattering Experiments and Models
Abstract
The objective of this project is to improve methods for acquiring acoustical signatures of targetsin water and models for understa"nding such signatures and methods of extracting, displaying,and using signatures. One of the approaches in the proposed research concerns aspects of targetresponses to acoustic radiation forces of focused sound beams. This component involveslaboratory experiments and development of underlying theory. Other components of the researchconcern complications resulting from target proximity to interfaces or target placement inwaveguides. Aspects of the research involve elastic responses of targets at high frequencies andassociated signature contributions. Related aspects concern the transmission of sound through thewalls of targets and associated contributions to signatures and acoustical images. These includelaboratory-based tests. This research should aid in discriminating between natural acoustic clutterand man-made objects of interest. Thus the research is relevant to improving the use of acousticscatte"ring for object identification and improving naval capabilities.
