Shape reconstruction of 2-D buried objects under a Kirchhoff approximation

The problem of reconstructing the shape of buried metallic objects for multifrequency plane wave incidence in a two-dimensional geometry is dealt with under the Kirchhoff approximation and solved by means of the singular value decomposition approach. Numerical results show the effectiveness of the solution method and outline the role of the parameters of the measurement configuration and of the properties of the ground on the features of the reconstruction.
