Claim 2:
3. The method of claim 2, wherein determining the offset location of the array phase center of the antenna array comprises:
determining a lateral offset of the array phase center between the determined beam peak direction and the radial direction, wherein the lateral offset is the lateral offset position of the probe antenna at the beam peak direction of AUT; and
determining a radial offset of the array phase center by fixing the lateral offset position of the probe antenna to the lateral offset position at the beam peak direction of AUT, and performing EIRP measurements at a plurality of near-field distances of the probe antenna in a direction of the fixed lateral offset position,
wherein absolute values of the near-field distances are to be determined, and intervals between adjacent ones of the near-field distances are known.
