f Datuming for Target Oriented Inversion in the k-w Domain

We have developed an algorithrn for linearized elastic inversion in the k -w domain (Bernasconi et al., 1994), based upon the extension to the elastic case of the diffraction tomography technique of Wu and Toksöz (1987) and the singular value decomposition of the transfer function between data and parameters (De Nicolao et al., 1993).
