Abstract :
A wide-band fiber-optic true-time-delay array receiver capable of receiving multiple independent beams simultaneously is demonstrated for the first time. The receiver is based on a dispersive prism technique and exhibits squint-free /spl plusmn/60/spl deg/ azimuthal steering of two simultaneous beams with no observable beam squint over a microwave component-limited bandwidth of 6-18 GHz.
