Abstract :
For pt.I see ibid., vol.39, no.3, p.672-82, 1991. The problem of estimating the location of a known scattering object from noisy, limited scattering data is solved within exact, scalar wave scattering theory. The estimation procedure is shown to be a generalization of an earlier procedure developed within the Born and Rytov approximations of weak scattering theory and is compared with that earlier procedure in a computer simulation study of electromagnetic tomography
