Application of Backscatter Models to SASS

Abstract

Historically, the main product of the Sonar Array Survey System (SASS) has been bathymetry. There is, however, much more information available in the SASS data. The acoustic data available offer the possibility of geoacoustic characterization of the seafloor. Using information extractable from SASS data, the geoacoustic characterization may be accomplished by the estimation of parameters of proposed backscatter models. Proposed backscatter models are presented, and several are considered in relation to the SASS data. Given backscatter strength data and bathymetric data, the possibility of the estimation of parameters for these models is considered. The utility of the model is dependent on the ability to estimate the parameters of the model. It is obvious for this reason that models with parameters that are easily and reliably estimated are best for practical purposes.
