发明名称 Method and apparatus for phased array antenna field recalibration
摘要 A system and method for calibrating a modular phased array antenna after replacement of a component of the modular phased array antenna including a plurality of sub-arrays, each sub-array including a plurality of antenna elements. A complex correction coefficient is determined for correcting a phase and amplitude of one antenna element of the antenna elements in a first sub-array of the sub-arrays. This correction coefficient is then applied to a plurality of the antenna elements in the first sub-array. Therefore, automatic calibration of an entire sub-array of an electronically scanned antenna may be accomplished in the field without the requirement for special test equipment, and with a reduced time and energy requirement because calibration of each individual antenna element in the replaced sub-array is not required.
