Abstract
A phased array radar has the ability to rapidly and adaptively position beams and adjust dwell times, thus enabling a single radar to perform multiple functions, such as surveillance, tracking and fire control. A radar resource manager prioritises and schedules tasks from the various functions to best use available resources. For networked phased array radars that are connected by a communication channel, this document considers whether coordinated radar resource management (RRM), which exploits the sharing of tracking and detection data between radars, enhances performance compared to Independent RRM. Two distinct architectures for Coordinated RRM are proposed, centralised management and distributed management, and characteristics of each architecture are specified. It is shown that different types of distributed management are possible, with each type characterised by varying amounts of coordination between the radars. A two-radar network and 30-target scenario are modeled in the simulation tool Adapt MFR, to analyse the performance of Independent RRM and two types of Coordinated RRM. Results indicate that the Coordinated RRM techniques achieve the same track completeness as Independent RRM, while decreasing track occupancy and frame time. Therefore, Coordinated RRM can improve reaction time against threats, at the expense of sending data across a communication channel.
