Abstract

We calculate the amplitude of acoustic monostatic and bistatic scattering from a solid wedge, thereby extending some previous work of ours that assumes a line source parallel to the edge of the wedge. The surface of the wedge is treated as an impedance surface, and the expression for the impedance corresponding to an absorbing, multilayered coating which had also been obtained by us previously is utilized here for calculating the scattering amplitude from the wedge coated with such an impedance material. Results are obtained as a function of frequency for various incident and bistatic angles. Calculations show in general a highly detailed interference structure except for the case of monostatic backscattering from an impenetrable wedge.
