Wideband Beampattern Synthesis Using Single Digital Beamformer With Integer Time Delay Filters

Existing wideband beampattern synthesis methods usually require multiple beamformers, each corresponding to one frequency bin, which results in excessive resource consumption in engineering practice. To alleviate the resource consumption of wideband array beamforming, we propose a novel time-domain...
