Shape reconstruction of 3D PEC: numerical results by the distributional approach

The problem of determining the shape of three dimensional perfect electric conducting (PEC) objects from the scattered far-field under the incidence of plane waves with a fixed angle of incidence and varying frequency is dealt with. The Kirchhoff approximation is employed and the object’s surface is represented as the support of a delta-distribution. Accordingly, the problem is cast as the inversion of a linear operator we deal with by means of the Truncated-Singular Value Decomposition. Numerical results are shown
