论文摘要
通过射频技术的进步，雷达和通信系统的收敛变得越来越有希望，并被设想为未来6G网络的关键特征。最近，引入了频率（FH）MIMO雷达以底层双功能雷达通信（DFRC）系统。优于以前以雷达为中心的DFRC设计，基于FH-MIMO雷达的DFRC（FH-MIMO DFRC）的符号率可以超过雷达脉冲重复频率。但是，许多实际问题，尤其是有关有效数据通信的问题，尚未解决/尚未解决。为了促进对新颖DFRC的认识和一般理解，本文致力于及时介绍FH-MIMO DFRC。我们全面回顾了新型DFRC的许多基本方面：信道/信号模型，信号传导策略，调制/解调处理和通道估计方法，仅举几例。我们还重点介绍了FH-MIMO DFRC中的主要剩余问题，并提出了潜在的解决方案，以阐明未来的研究工作。
Enabled by the advancement in radio frequency technologies, the convergence of radar and communication systems becomes increasingly promising and is envisioned as a key feature of future 6G networks. Recently, the frequency-hopping (FH) MIMO radar is introduced to underlay dual-function radar-communication (DFRC) systems. Superior to many previous radar-centric DFRC designs, the symbol rate of FH-MIMO radar-based DFRC (FH-MIMO DFRC) can exceed the radar pulse repetition frequency. However, many practical issues, particularly those regarding effective data communications, are unexplored/unsolved. To promote the awareness and general understanding of the novel DFRC, this article is devoted to providing a timely introduction of FH-MIMO DFRC. We comprehensively review many essential aspects of the novel DFRC: channel/signal models, signaling strategies, modulation/demodulation processing and channel estimation methods, to name a few. We also highlight major remaining issues in FH-MIMO DFRC and suggest potential solutions to shed light on future research works.
