Abstract:
Phased array antenna system operated from a remote location. Operations at a radio hub location involve generating an RF signal and modulating with the RF signal a continuous wave optical carrier to produce a transmit modulated optical carrier (TMOC). Electronic control signal digital data is also generated at the radio hub to control an antenna beam pattern of an array antenna. The control signal digital data is used to modulate an optical carrier for generating a control signal modulated optical carrier (CSMOC). Both the TMOC and CSMOC are coupled to an optical fiber for communication to an antenna site remote from the radio hub location. At the antenna site, the CSMOC and TMOC are processed to recover the electronic control signal digital data and a plurality of transmit element level modulated RF (ELMRF) signals which are applied to array antenna elements.
