Claim 9:
10. The method of claim 9, wherein for each loop of the loop procedure, compensating for the measured antenna patterns for probe gain and path loss difference comprises:
determining an included angle between the probe antenna to the array phase center of the antenna array and a bore of sight of the probe antenna;
determining an actual probe gain to the array phase center of the antenna array, wherein an opposite number of the actual probe gain is used as a compensation curve for compensating the probe antenna pattern;
determining a distance between probe antenna and the array phase center of the antenna array;
calculating a ratio of the determined distance to a radius length of the probe antenna to the center of quiet zone; and
using the ratio to compensate for distortion caused by path loss variation.
