摘要
雷达通信一体化技术作为电子信息领域的前沿研究热点,其核心目的在于通过共享硬件平台以及协同调度时-频-功率资源,实现雷达探测与通信传输任务的共同部署,从而解决频谱资源日趋紧张与用频设备指数增长之间的矛盾,为高效利用频谱资源提供新的路径。为此,系统地梳理了国内外针对雷达通信一体化的研究进展:首先,介绍了雷达通信一体化技术的演进脉络与发展趋势;随后,从发射机的一体化波形和波束赋形设计、接收机的信号处理2个层面对现有雷达通信一体化的研究进行了归纳总结;最后,展望了未来雷达通信一体化的发展方向及关键技术挑战。
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.
