Abstract

Nonlinear tomographic reconstruction algorithms are developed for inversion of data measured in scattering experiments in which the scattered wavefields are modeled by an arbitrarily large number of terms in the Born series. The algorithms attain the form of a Volterra series of nonlinear operators, with the usual filtered backpropagation algorithm of diffraction tomography as the leading linear term
