Abstract
In the present paper, we propose a numerical technique describing the scattering of an acoustic wave interacting with a sharp wedge immersed in water considered as homogeneous. The calculations are limited to t he angular variations of the acoustic field scattered in a plane perpe ndicular to the edge of the wedge. The theoretical angular plots which point out maxima in particular directions are compared with the exper imental measurements. We notice a good agreement between the two deter minations.
