An efficient technique to correct the positioning errors in the near-field – far-field (NF–FF) transformation with planar wide-mesh scanning (PWMS) is developed and experimentally validated. It is based on a nonredundant sampling representation of the voltage measured by the scanning probe obtained by considering the antenna as enclosed in an oblate ellipsoid. An iterative technique is applied to retrieve the NF data at the points fixed by the sampling representation from the acquired nonuniformly spaced ones. Once the uniform PWMS data have been recovered, those needed by the classical plane-rectangular NF–FF transformation are efficiently evaluated by using an optimal sampling interpolation algorithm.

Abstract
An efficient technique to correct the positioning errors in the near-field – far-field (NF–FF) transformation with planar wide-mesh scanning (PWMS) is developed and experimentally validated. It is based on a nonredundant sampling representation of the voltage measured by the scanning probe obtained by considering the antenna as enclosed in an oblate ellipsoid. An iterative technique is applied to retrieve the NF data at the points fixed by the sampling representation from the acquired nonuniformly spaced ones. Once the uniform PWMS data have been recovered, those needed by the classical plane-rectangular NF–FF transformation are efficiently evaluated by using an optimal sampling interpolation algorithm.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
