Abstract
A method for measuring the far field antenna pattern of a large phased array antenna on a conventional far field range by applying a correction factor to the antenna phase shifters. As the antenna is electronically steered to each of its scan angle, a particular correction factor is applied to each radiating elements to correct the far field antenna pattern to the shortened far field range.
