Abstract

Summary

Density inversion is a difficult task in the mechanical properties estimation of subsurface targets, because it has more complicate scattering characteristics associated with random scattering angle. Recently, we have presented an approach to handle nonlinear inverse scattering problem in acoustic constant density media by taking into account the combination of second-order Born approximation and GRT inversion ( ). In this study, we extend the approach to the acoustic two-parameter media (density and bulk modulus) by appropriately dealing with high order derivatives arising from the density perturbation and double scattering from a local area. We test our method for models composed of two flat layers. The numerical experiments demonstrate that the linear single scattering inversion is good in amplitude for weak perturbation (less than 5%) of the background media, and our approach can work for up to 40% or more for density-only variations and 12% for simultaneous variations of density and velocity, which makes the migration inversion more accurate.
