Joint radar and communication (JRC) has recently attracted substantial attention. The first reason is that JRC allows individual radar and communication systems to share spectrum bands and thus improves the spectrum utilization. The second reason is that JRC enables a single hardware platform, e.g., an autonomous vehicle or a UAV, to simultaneously perform the communication function and the radar function. As a result, JRC is able to improve the efficiency of resources, i.e., spectrum and energy, reduce the system size, and minimize the system cost. However, there are several challenges to be solved for the JRC design. In particular, sharing the spectrum imposes the interference caused by the systems, and sharing the hardware platform and energy resource complicates the design of the JRC transmitter and compromises the performance of each function. To address the challenges, several resource management approaches have been recently proposed, and this paper presents a comprehensive literature review on resource management for JRC. First, we give fundamental concepts of JRC, important performance metrics used in JRC systems, and applications of the JRC systems. Then, we review and analyze resource management approaches, i.e., spectrum sharing, power allocation, and interference management, for JRC. In addition, we present security issues to JRC and provide a discussion of countermeasures to the security issues. Finally, we highlight important challenges in the JRC design and discuss future research directions related to JRC.

联合雷达和通信中的无线电资源管理:综合调查



联合雷达和通信(JRC)最近引起了广泛关注。第一个原因是JRC允许单独的雷达和通信系统共享频段,从而提高频谱利用率。第二个原因是JRC使单个硬件平台(例如自动驾驶汽车或无人机)能够同时执行通信功能和雷达功能。因此,JRC能够提高资源(即频谱和能源)的效率,缩小系统规模,并最大限度地降低系统成本。然而,JRC 设计还有几个挑战需要解决。特别是,共享频谱会带来系统造成的干扰,共享硬件平台和能源资源使JRC发射机的设计变得复杂,并损害了各个功能的性能。为了应对这些挑战,最近提出了几种资源管理方法,本文对 JRC 资源管理进行了全面的文献综述。首先,我们给出 JRC 的基本概念、JRC 系统中使用的重要性能指标以及 JRC 系统的应用。然后,我们回顾并分析了 JRC 的资源管理方法,即频谱共享、功率分配和干扰管理。此外,我们向 JRC 提出安全问题,并讨论安全问题的对策。最后,我们强调了 JRC 设计中的重要挑战,并讨论了与 JRC 相关的未来研究方向。
