An efficient probe compensated near-field – far-field (NF–FF) transformation technique with spherical scanning for noncentred antennas, which requires a minimum number of NF data, is developed in this work, by applying the nonredundant sampling representations of electromagnetic field and modelling the antenna under test (AUT) by a sphere. The interest for it arises from the fact that, for practical constraints, it could be not possible a centred mounting of the AUT on the scanning sphere centre. In fact, the number of NF data needed by classical spherical NF–FF transformation can considerably grow for an offset mounting, due to the increase of the radius of the minimum sphere containing the AUT and centred on the scanning sphere centre.
