ABSTRACT

The Born series solution of the Lippmann-Schwinger equation plays an important role in inverse scattering theory and full waveform inversion. A common issue of this method is the divergence of the series solution in strong scattering media. This abstract presents a comparison of two convergent scatteringl series, refered to as convergent Born series (CBS) and renormalized Born series (RBS) based the renormalization group theory, for frequency-domain seismic modeling in strong scattering media. The first method employs a damped parameter and a preconditioner to make the summation of the series stepbystep. The second method applies the renormalization group (RG) theory to the iteration form of the conventional Born series. Numerical examples demonstrated that both the convergent and renormalized Born series can converge absolutely in strong scattering media.
