Resource Allocation in Networked Joint Radar and Communications

Abstract

In today's world, particularly in civilian sectors where situational awareness is paramount, research is being conducted on concepts that enable the joint realization of both sensing and communication functions with the upcoming 6G technology planned for near-future deployment, especially in sectors like automotive. On the other hand, efforts in the military domain to enhance situational awareness and counter evolving air threats have gained momentum with the development of systems incorporating multiple sensors for joint operation, known as radar network architectures. However, when multiple radar systems operate together, bandwidth allocation must be performed in order to avoid interference. As a contribution to the literature, this study proposes a joint radar and communication network concept applied to air defense systems, aiming to enhance their situational awareness by adopting the joint radar and communication concept commonly addressed in civilian applications. Additionally, a resource optimization problem has been addressed to maximize the performance of both radar and communication functions within the joint radar and communication network. © 2024 IEEE.
