Abstract:

Dual-function radar and communication (DFRC) technology, as a cutting-edge research focus in the field of electronics and information, aims to resolve the contradiction between increasingly scarce spectrum resources and the exponential growth of frequency-using devices. By sharing hardware platforms and coordinating time-frequency-power resource scheduling, it enables the simultaneous deployment of radar detection and communication transmission tasks, thereby providing innovative pathways for efficient spectrum utilization. This paper systematically reviewed global research progress in DFRC: firstly, it introduced the evolution and development trends of DFRC technology; subsequently, it comprehensively summarized the existing research on DFRC from two key aspects, namely the integrated waveform and beamforming design at the transmitter, and the advanced signal processing techniques at the receiver; finally, it looked forward to the future development direction and key technical challenges in this field.
