Abstract:

We intend to develop physics-based models of acoustic wave propagation and scattering in complex media that could help to predict backscattering and forward scattering by marine animals by applying dat-based signal processing techniques for understanding and characterizing biological-acoustical coupling in acoustic propagation and scattering. The objective of our research to develop data-based sensitivity kernel analysis methods to determine the location and potentially scattering properties of individual scatterers embedded in a complex propagation environment. The approach is to collect data in an laboratory setting and then develop and apply a data-based sensitivity analysis to locate the scatterers and potentially determine their cross sections.
