Joint radar and communication: A survey

Abstract

Joint radar and communication (JRC) technology has become important for civil and military applications for decades. This paper introduces the concepts, characteristics and advantages of JRC technology, presenting the typical applications that have benefited from JRC technology currently and in the future. This paper explores the state-of-the-art of JRC in the levels of coexistence, cooperation, co-design and collaboration. Compared to previous surveys, this paper reviews the entire trends that drive the development of radar sensing and wireless communication using JRC. Specifically, we explore an open research issue on radar and communication operating with mutual benefits based on collaboration, which represents the fourth stage of JRC evolution. This paper provides useful perspectives for future researches of JRC technology.

An Overview of Signal Processing Techniques for Joint Communication and Radar Sensing

“…These categories of joint systems have been receiving strong and growing research interest, with results having been reported under various names, such as Radar-communications (RadCom) [1], joint radar (and) communications (JRC) [7], [9], [11], joint communication (and) radar (JCR) [20], [22], joint communication and radar/radio sensing (JCAS) [23], [24], dual-function(al) radar communications (DFRC) [4], [10], [25], [26], and more recently, integrated sensing and communications (ISAC). The first three typically refer to a general joint system and can be used interchangeably.…”

“…There exist some excellent overview articles on JCR, particularly on system and signal modelling. For example, [1] provides a foundational review of signal models for basic single carrier and multicarrier JCR systems; [3], [6], [11] cover C&R systems from coexistence, cooperation, to co-design; [4], [8] survey radar-centric DFRC systems, with a focus on signal embedding; [7] delivers an excellent review on the evolution of JCR systems and their potential applications; [12] provides an overview on mobile network JCR systems; [9], [10], [13] overview millimeter-wave JCR systems for automotive networks, providing detailed signal models. However, the topic of receiver signal processing, which is critical for the viability and performance of the JCR systems, has not been adequately covered by the aforementioned literature.…”

6G vision: An ultra-flexible perspective

“…Context-awareness is used to optimize network architectures in wireless communications [118]. ISAC systems are studied for radar sensing [91,119] and Wi-Fi network coexistence [120] in the literature. However, the complete list of sensing information that can be useful for the next generation cellular communications systems from the ISAC perspective has not yet been comprehensively studied [114].…”

OFDM-IM for Joint Communication and Radar-Sensing: A Promising Waveform for Dual Functionality

“…From the signal processing perspective, Mishra et al (2019) dived in to mm-Wave JCR systems and waveform design. As a further note, Feng et al (2020) explored state-of-the-art JCR evolution with a comprehensive survey on the DFRC technology.…”
