Optical control of array antennas in a radar and communication application i s described. The opto-electronic architecture simplifies the antenna element interface un it (AEIU) by executing the phase control function in a central processor unit, thus lowering the fabrication cost, and providing greater stability of the phase control. This architecture further eliminates the need for a distribution network for the phase control information. Dynamic amplitude control is performed in a specific number of locations. Signal distribution is done through a fiber-optic network allowing a more flexible and lighter distribution network with lower propagation loss and immunity to electromagnetic interference.
