Frequency-comb-steered ultrawideband quasi-true-time-delay beamformer for integrated sensing and communication

Abstract Ultrawideband beamforming is essential for next-generation radar and communication systems, however, the instantaneous bandwidth of phase-shifter-based phased array antennas (PAAs) is limited by beam squint. Photonic true-time-delay (TTD) beamformers offer a potential solution, yet their pr...
