Paper Abstract

We present the analytical description of a photorefractive phased array beamforming system using the BEAMTAP (Broadband and Efficient Adaptive Method for True-Time-Delay Array Processing) algorithm for a large N-element array that requires only 2 tapped delay lines (TDLs) instead of the conventional N TDLs. Simulation results indicate that the processor is able to adapt to a broadband signal of interest at a specific angle of arrival. We show that the system produces a coherent sum of the desired signals from the phased array, with the corresponding time delays appropriately compensated for in an adaptive fashion without prior knowledge of the angle-of-arrival.
