Mobile Digital Communications Using Phase Conjugating Arrays

A phase conjugation based method for full-duplex digital communications is discussed. The method uses a spatially confined and directive antenna pattern while a fullduplex digital communications link is maintained between moving platforms. The communications abilit~ of the array is based on processing the phase associated with the message and the phase associated with the platform’s motion separately. Preliminary measurements at 6 GHz indicate that the phase conjugation method does allow simulators tracking and communications.
