Abstract

The inverse problem concerning the identification of rigid surfaces of scattering objects formulated in the frequency domain is presented in this paper. Differences in the identification of concave objects, such as kite-shaped, and convex objects (circle) are indicated. The reader’s attention is focused on the conventional boundary element method with small number of boundary elements and the small number of sensors, which is significant for inverse problems.

Keywords:

acoustics wave scattering by arbitrary shaped objects, simulation of external acoustic problems using the Boundary Element Method (BEM), inverse problem
