A description of an analytical algorithm for determining the shape of the scatterer with acoustically rigid walls is given for low-frequency scattering of plane acoustic waves. It is assumed that the amplitude of the scattering is known in a direction close to the direction of backward scattering, specified on a discrete set of probing wave numbers. The incident wavelength is of the order of the length of the scatterer and is much greater than its thickness.
