Radio Resource Management in Joint Radar and Communication: A Comprehensive Survey
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
