Abstract:We present a theory of acoustic tomography based on data processing shear wave scattered field over an observational plane, including frequency and polarization diversities. The theory is based on the Gubernatis formulation of scattering and does not require solution of the Fredholm equation for material displacement u. An essential feature of the theory is an expansion of VjkUk in even powers of frequency to obtain an "equivalent frequency insensitive" source in the anomaly.We treat data inversion both in car… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
