Abstract
On an element-by-element basis, measure phases between signals at Port A to Port B of the antenna feed network to get a phase measurement angle that corresponds to an angular difference between outgoing radar signals and target echo return signals; apply a least squares fit equation to the angular distance to get a correction phase slope across the array, &dgr; , and applying a phase slope correction of &dgr; to the phases of the transmitted signal.
