Method and device for error correction of active phased array antenna system

摘要

The present invention relates to a method and apparatus for correcting an error of an active phased array antenna system, and more particularly, extracting characteristics of a semiconductor transceiver composed of a combination of numerous transceiver modules, and using this to correct errors in the signal transmission and reception process It relates to an error correction method and apparatus of an active phased array antenna system. An error correction apparatus for an active phased array antenna system according to an embodiment of the present invention includes a semiconductor transceiver comprising a plurality of semiconductor transceivers; an amplifier for outputting a test signal for detecting transmission characteristic values of a plurality of semiconductor transceivers; a transmission path used for signal transmission and formed between the RF transmission output terminal of the amplifier and the RF input terminal of a plurality of semiconductor transceivers; a correction signal distributor for collecting and distributing transmission characteristic values from a plurality of semiconductor transceivers to which test signals are input through transmission paths; a receiver including C1 to CJ reception channels used when detecting transmission characteristic values of a plurality of semiconductor transceivers; a receiver correction signal distributor for distributing the transmission characteristic values collected through the correction signal distributor to C1~CJ reception channels of the receiver; and an antenna compensator for generating a lookup table of transmission correction values of the semiconductor transceiver by using transmission characteristic values stored in C1 to CJ reception channels of the receiver.
