In this paper the linear synthetic aperture focusing technique (SAFT), the nonlinear contrast source inversion (CSI) algorithm and the CSI algorithm with extended approaches, such as frequency approach and regularization approach, are applied to reconstruct a complicated target immersed in water from the experimental elastic wave data. The inversion results from these datasets using multi-bistatic measurement, which are obtained in the acoustic wave case and the pressure and vertically polarized shear (P-SV) wave case, verify the CSI algorithm with extended approaches is an accurate and promising method for elastic wave imaging.
