Systems and methods are provided for phased array passband calibration, which permits repeated calibration of the antenna system in the field without a moving far field sensor. An implementation includes an equalization filter coupled to a phased array feed; a calibration probe disposed to couple with an antenna array to transfer radio frequency (RF) energy; a database of probe-to-far-field (FF) transforms having a probe-to-FF transform for each of a plurality of incidence angles; a calibration component operable to: receive calibration probe measurements for a plurality of frequencies; and determine a calculated phased array passband response for at least a first incidence angle, based at least on the calibration probe measurements and a probe-to-FF transform for the first incidence angle; and a filter generation component operable to generate a tuning configuration for the equalization filter, based at least on the calculated phased array passband response.
