Interpretive Migration Velocity Analysis with Applications to GPR

Velocity model refinement by a combination of Deregowsky and focusing techniques is an effective solution to image complex shallow subsurface conditions by means of GPR. Including geological knowledge in the velocity analysis of CRP gather considerably reduces costs and uncertainties of the final velocity model and allows rapid convergence to the correct solution. Applications to high resolution GPR study of alluvial sediments confirm the accuracy of the results attainable by PSDM in imaging complex sedimentological patterns.
