32. α). (cf. Ref. 36). This relation between the radiating sources in the scattering spectrum and the spatial spectrum of the inhomogeneity to be reconstructed is a consequence of using the Born single-scattering approximation which is valid only in the case of weak perturbations of the refraction index. If the deviations of the local sound speed from a certain mean level are appreciable, the reconstruction algorithms must take multiplescattering effects into account, as for example in D. T.
