The evaluation of the number of degrees of freedom (NDF) of scattered fields in strip geometries from the far-zone under the Born approximation is pointed out. The analysis is performed employing the singular-value decomposition (SVD) of the scattering operator in the one-dimensional scalar case of one or more strips illuminated by a TM polarized plane wave. It is known that investigating the scattering scene by plane waves from different angles of incidence (multi-view configuration) enhances the NDF. We mean investigating the minimum number of incident plane waves providing the NDF of the scattered fields both by theoretical estimations and by numerical verifications.

Abstract
The evaluation of the number of degrees of freedom (NDF) of scattered fields in strip geometries from the far-zone under the Born approximation is pointed out. The analysis is performed employing the singular-value decomposition (SVD) of the scattering operator in the one-dimensional scalar case of one or more strips illuminated by a TM polarized plane wave. It is known that investigating the scattering scene by plane waves from different angles of incidence (multi-view configuration) enhances the NDF. We mean investigating the minimum number of incident plane waves providing the NDF of the scattered fields both by theoretical estimations and by numerical verifications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
