ACCURATE AUTO-CALIBRATION OF PHASED ARRAY ANTENNAS

摘要

A method and apparatus is disclosed that is capable of verifying on site the health, calibration and integrity of individual phased array modules of a phased array antenna system and, in certain cases, enabling the phased array antenna system to overcome element failures by use of a beam-steering computer (i.e. beamsteering). The present disclosure provides a test probe or RF radiator in or adjacent the antenna array for supplying and receiving test and calibration signals.
