Acoustic Coherent Backscatter Enhancement from Aggregations of Point Scatterers
Department of Mechanical Engineering, University of Michigan Ann Arbor United States
Pagination or Media Count:
The overall long-term goal for this project is to determine if and how acoustic coherent backscatter enhancement ACBE can be used for classification of active sonar returns in a wide variety of ocean environments. During its first four years, this project has focused on simulations of near- and far-field acoustic multiple scattering from two- and now three-dimensional aggregations of omnidirectional point scatterers to determine the parametric realms in which ACBE might be observed, and its characteristics when it is observed.
