Certain simplified variants of a previously proposed iterational algorithm for solving inverse scattering problems with consideration of rescatterings of a wave which probes a heterogeneity are examined. The errors in restoration of the function which describes this particular heterogeneity are estimated. They form due to the introduced simplification. A solution method is proposed which makes it possible to greatly accelerate restoration of the disperser. The effectiveness of the method is illustrated by some results from a model experiment.
