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