An effective technique to compensate known positioning errors in a nonredundant near field - far field (NF-FF) transformation with plane-polar scan, using an oblate ellipsoid to model the antenna under test, has been experimentally validated at the UNISA Antenna Characterization Lab.

Abstract

An effective technique to compensate known positioning errors in a nonredundant near field - far field (NF-FF) transformation with plane-polar scan, using an oblate ellipsoid to model the antenna under test, has been experimentally validated at the UNISA Antenna Characterization Lab. It employs the singular value decomposition method to retrieve the probe voltage samples at the points fixed by the nonredundant sampling representation from the acquired irregularly spaced ones. The NF data needed by the classical plane-rectangular NF-FF transformation are then efficiently evaluated by means of an optimal sampling interpolation expansion.
