A highly-directional FPGA-based broadband beamformer is proposed using a novel 3D HR plane-wave digital filter. This filter acquires the 3D spatio-temporal input signals from a spatiallyrectangular arrays of sensors that is scanned by only one time-multiplexed A/D converter. The proposed architecture employs a novel scanned-array 3D parallel vector-processor (VP), clocked at 80 MHz, and has the potential to achieve real-time broadband plane-wave filtering on a single low-cost integrated circuit at spatial frame-rates of 19 kHz over a 64 by 64 spatial broadband sensor array. © 2006 IEEE.
