Abstract :
An active antenna array system, capable of switching between sum and difference patterns for radar applications, is explored. The desired phase relationship amongst antenna elements is synthesized via injection locking. Optical reference signal is transmitted from remote controller through optical fiber link. Measured patterns agree with theoretical results.<>
