Abstract: A system and method for testing an antenna-under-test (AUT). A multi-probe antenna array transmitter is moved to a plurality of positions within a scan area. At each position, each probe antenna element of the transmitter transmits a near-field (NF) over-the-air (OTA) signal to the AUT. An alignment procedure is performed to align transmission locations for signals transmitted by different ones of the plurality of probe antenna elements. Correction factors are determined that characterize amplitude and phase discrepancies between the probe antenna elements of the transmitter. The correction factors are applied to the signals, and the corrected signals are combined at each transmission location to obtain average signals. A far-field (FF) reception pattern for the AUT is determined based on a discrete Fourier transform of the average signals and stored in a non-transitory computer readable memory medium.
