摘要：

A numerical method for a three-dimensional inverse acoustic scattering problem is considered. From the knowledge of several far fields patterns of the Helmholtz equation a closed surface partial derivative D representing the boundary of an unknown obstacle D is reconstructed. The obstacle D is supposed to be acoustically soft or acoustically hard or characterized by a given acoustic impedance.
