Conclusion

This paper introduces an approach to waveform inversion that builds from the WEMVA theory developed by Sava and Biondi (2004). The main differences between the this approach and that of Pratt and Worthington (1989) is that this formalism provides a scattering operator that permits a direct estimate of the slowness perturbation. Future work will implement this scheme into a transmission wavefield WEMVA scheme.
