Dual-function radar-communication (DFRC), as an integration of radar and communication functionality, has been envisioned as a promising technology for B5G and 6G. Nowadays, by integrating millimeter wave (mmWave) DFRC and massive multiple-input multiple-output (MIMO), the DFRC can achieve high-precision sensing while guaranteeing high-throughput communications. However, implementing mmWave massive MIMO DFRC systems with fully digital beamforming architecture is impractical due to the substantial power consumption and prohibitive hardware cost. As a cost-effective alternative, the DFRC equipped with hybrid beamforming (HBF) architecture is envisioned as a good trade-off between system performance and hardware complexity. In this chapter, two cases of HBF design for mmWave DFRC systems are studied. Specifically, in the first case, we consider a scenario in which a single-carrier DFRC system communicates with a single multi-antenna user while detecting an extended target in the presence of extended clutters. In the second case, a multi-user and multi-carrier DFRC system is investigated, where this system leverages multi-carrier signals to achieve high-accuracy direction of arrival estimation and ensure high-quality communication services. Two state-of-the-art HBF design algorithms are proposed for the two cases under consideration. Numerical results are provided to validate the effectiveness of the proposed algorithms and superiority of mmWave DFRC with HBF architecture..

As a promising technology in beyond-5G (B5G) and 6G, dual-function radar-communication (DFRC) aims to ensure both radar sensing and communication on a single integrated platform with unified signaling schemes. To achieve accurate sensing and reliable communication, large-scale arrays are anticipated to be implemented in such systems, which brings out the prominent issues on hardware cost and power consumption. To address these issues, hybrid beamforming (HBF), beyond its successful deployment in communication-only systems, could be a promising approach in the emerging DFRC ones. In this article, we investigate the development of the HBF techniques on the DFRC system in a self-contained manner. Specifically, we first introduce the basics of the HBF based DFRC system, where the system model and different receive modes are discussed with focus. Then we illustrate the corresponding design principles, which span from the performance metrics and optimization formulations to the design approaches and our preliminary results. Finally, potential extension and key research opportunities, such as the combination with the reconfigurable intelligent surface, are discussed concisely.
