摘要

The challenges of imaging beneath the complex salt canopies of the Gulf of Mexico and other areas of the world are well known. The complex wavefronts generated by the anisotropic velocity regimes and high reflection angles in these areas cause problems with illumination and also create complications in imaging. The absorption properties of the salt boundaries and heterogeneities within the salt mean that only the lowest frequencies penetrate to the structure beneath, causing a loss of resolution.
