The reconstruction of the shape of "strongly scattering" objects from the knowledge of the scattered field is investigated. With reference to perfectly conducting cylinders, the provided formulation accommodates the distribution nature of the induced surface current density. Thus, as unknown representing the objects' contour, a single layer distribution is chosen so that the boundary of the scatterers is described by its support. The non-linear unknown-data mapping is linearized by means of the Kirchhoff approximation and the inversion is performed by an extended SVD approach.

Abstract
The reconstruction of the shape of "strongly scattering" objects from the knowledge of the scattered field is investigated. With reference to perfectly conducting cylinders, the provided formulation accommodates the distribution nature of the induced surface current density. Thus, as unknown representing the objects' contour, a single layer distribution is chosen so that the boundary of the scatterers is described by its support. The non-linear unknown-data mapping is linearized by means of the Kirchhoff approximation and the inversion is performed by an extended SVD approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
