Abstract
A system and method for determining the location of the phase center of an antenna are provided. For the transverse location of the phase center, the system may include radio frequency (RF) probes symmetrically surrounding the antenna's geometrical center to define RF probe pairs, a plurality of phase detectors for determining a phase difference between the signals detected by each pair and a processor for determining the transverse location of the phase center based upon probe position and the phase differences. For the longitudinal location of the phase center, the system may include first and second RF probes having a common transverse position, but being longitudinally separated, a phase detector for determining a phase difference between the signals detected by the probes and a processor for determining the longitudinal location of the phase center based upon the longitudinal separation and the phase difference.
