Description

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.
