ABSTRACT:
A system architecture based on optical heterodyne transmission of signals from input (12) to antenna array (26), and vice versa, is provided. The system is based on conventional concepts of coherent, multichannel switching systems. The coherent optically controlled phased array antenna system of the invention comprises a transmitter system (10) and a receiver system (46). Due to their similar device requirements, it is possible that the same system can be switched from transmit to receive without introducing undo complexity into the architecture.
