he Phalcon NT Transponder is a marine radar beacon system (RACON) capable of responding to S-band and X-band pulsed radars in compliance with the ITU recommendations ITU-R M.824-4 ‘Technical Parameters of Radar Beacons’. The RACON is a receiver/transmitter transponder device used as a navigation aid, identifying landmarks or buoys on a shipborne marine radar display.
