Abstract

In this paper we apply the linear synthetic aperture focusing technique (SAFT), and the nonlinear contrast source inversion (CSI) algorithm and the CSI algorithm with extended approaches, to reconstruct a complicated target immersed in water from the experimental elastic wave data. The inversion results, which are obtained in the acoustic wave case and the pressure and vertically polarized shear (P-SV) wave case, prove that the CSI algorithm with extended approaches is an accurate and efficient method for elastic wave imaging.
