A method for estimating sound velocity distribution of a scattering medium is developed. The sound velocity is estimated by iterating the WKB (Wentzel, Kramers and Brillouin) approximation for the calculation of the scattered field. The iterative procedure incorporates "simulated annealing" for determining of the optimal distribution of sound velocity. Estimations for the cylinder and 2-layer cylindrical shell models are carried out numerically and experimentally. The estimated sound velocity agrees well with the original distribution.
