In this work, the desirability of a true time-delay beamformer is briefly discussed. Experimental results are reviewed and fundamental systems calculations are reported. Results for both optical and radar performance specifications were obtained, based upon a mathematical model of the photonic delay line developed by the author. These results address the use of the photonic delay line in a standard radar beamformer. Future work will evaluate the performance of the photonic beamformer in adaptive processing.
