| This talk is concerned with the inverse problem of reconstructing an inhomogeneous medium from the acoustic far-field data. The contrast source inversion (CSI) methods are the well-known algorithms for such kind of inverse scattering problem, which are very fast and efficient. Recently, we propose two iterative regularized CSI-type methods. Our methods have very low computational complexity. Moreover, we prove the global convergence of the proposed methods. Numerical experiments show that our methods are very robust and have faster convergence rates than the original CSI-type methods. |
