摘要:

联合雷达和通信(JRC)最近引起了极大的关注。第一个原因是JRC允许各个雷达和通信系统共享频谱带,从而提高频谱利用率。第二个原因是JRC支持单个硬件平台,例如,自动驾驶车辆或无人机,以同时执行通信功能和雷达功能。因此,JRC能够提高资源的效率,即,频谱和能量,减小系统尺寸,并最小化系统成本。然而,对于JRC设计来说,有几个挑战需要解决。特别是,共享频谱会增加系统造成的干扰,共享硬件平台和能源会使JRC发射机的设计变得复杂,并损害每个功能的性能。为了应对这些挑战,最近提出了一些资源管理方法,本文对JRC的资源管理进行了全面的文献综述。首先,我们给出了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,我们回顾和分析资源管理方法,即,频谱共享、功率分配和干扰管理。此外,我们提出的安全问题,以JRC和提供的安全问题的对策进行了讨论。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。

英文摘要:

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.
