In terms of target detection and classification, scattering from exposed rock on the seafloor, i.e., individual rocks and rock outcrops presents some of the most difficult challenges for modern MCM and ASW sonar systems in shallow water. Work on characterizing, modeling and simulating mean levels, and other statistical measures of acoustic scattering from rocks and rock outcrops is therefore critical. Unfortunately information on scattering from underwater rock and outcrops is almost non-existent. The primary long-term goal of this research project is to increase understanding and modeling capabilities for high-frequency acoustic scattering from rock and rock outcrops. In addition to an increase in basic understanding of the characteristics of scattering from rock, any resulting advances in modeling would be useful for improving simulation capabilities and for improving detection and classification tools.
