Second order, iterative least squares inversion of dispersive reflections

Scott Keating and Kris Innanen

ABSTRACT

A second order, iterative least squares approach to anacoustic inversion is presented and tested. Results are compared to linearized inversions, and failure regions and their causes are explored. While the second order approach offers improvement over the linearized approach, problems associated with very low and high Q are caused by other factors and are not greatly improved by the second order inversion.
