Spherical Near-Field Antenna Measurements - A Review of Correction Techniques

Author: Doren W. Hess
Publication: EuCAP 2007
Copyright Owner: IET

Following an introductory review of spherical near-field scanning measurements, with emphasis on the general applicability of the technique, we present a survey of the various methods to improve measurement accuracy by correcting the acquired data before performing the transform and by special processing of the resulting data following the transform. A post-processing technique recently receiving additional attention is the IsoFilter™ technique that assists in suppressing extraneous stray signals due to scattering from antenna range apparatus.
