- W2032060014 abstract "In this paper, the multidimensional inverse scattering problem for an acoustic medium is formulated as a generalized tomographic problem. The medium is probed by wide-band plane-wave sources, and the scattered field is observed along straight-line receiver arrays. The objective is to reconstruct, simultaneously, the velocity and density profiles of the medium. Using the Born approximation and applying a proper filter to the observed scattered field, generalized projections of the velocity and density scattering potentials are obtained. The generalized projections are weighted integrals of the scattering potentials; in two dimensions, the weighting functions are concentrated along parabolas, in three dimensions, they are concentrated over circular paraboloids. The resulting problem of generalized tomography (or inverse generalized Radon transform, or integral geometry) is solved in exact analytical form. The solution is expressed as a backprojection operation followed by a two- or three-dimensional space-invariant filtering operation. In the Fourier domain, the resulting image is a linear combination of the velocity and density scattering potentials, where the coefficients depend on the angle of incidence of the probing wave. Therefore, in principle, two experiments with different angles of incidence are necessary to reconstruct the velocity and density scattering potentials separately. It is shown that this involves a numerically unstable procedure, especially for bandlimited data, necessitating the use of several angles of incidence to regularize the inversion." @default.
