Modern radars use phased array antenna technology, which allows the radar beam to be steered and waveforms varied almost instantaneously. This flexibility makes a phased array radar well suited to performing multiple functions concurrently, such as search, tracking and fire control. The execution of multiple functions necessitates the study of radar resource management (RRM), which considers how to allocate the finite radar time/energy budget between radar tasks and to schedule the tasks, in order to maximize radar performance. Given the variety of missions that a military platform must undertake, the most effective RRM techniques adapt to the radar’s current sensing environment. Adaptive RRM involves dynamic, time-varying optimization of radar resources to optimize radar performance in challenging, target-rich environments. This activity addresses the Long Term Capability Requirements for Intelligence Surveillance & Reconnaissance (ISR) Collection Capability and for Active Ballistic Missile Defence. This activity also addresses the Defence Against Terrorism Requirement for Protecting Harbours and Vessels from Surface Threats.


The RTG will undertake research in Adaptive RRM for phased array radars, with the following specific objectives: 1) Define “RRM services” in place of function, and define key elements and metrics for Quality of Service. 2) Establish definitions and Figures of Merit (FoM) for phased array radar performance and RRM evaluation. 3) Consider how Adaptive RRM algorithms can be evaluated in simulation through the use of benchmark test scenarios of increasing complexity. 4) Formulate and assess Adaptive RRM techniques for naval, airborne and surface phased array radars. Evaluate performance against the benchmarks scenarios and established metrics. 5) Establish metrics for the performance of a sensor suite on a single platform. Formulate and assess techniques for the concurrent and collaborative management and performance optimization of sensors when receiving coordination data/commands from other sensors within the sensor suite.


a) Establish common definitions and FoM (Figures of Merit) for phased array radar operation and performance. b) Define terms and metrics for Quality of Service. c) Develop benchmark test scenarios of varying complexity for standardising RRM analysis. d) Formulation of a common framework for tracking and surveillance. e) Scheduling of track updates for multiple target tracking. Solutions will be evaluated with respect to the definition of “Track Quality”. f) Optimization of RRM for coalition force-level planning (understanding the best mix and employment of ground, maritime and airborne platforms). g) RRM for radars which are connected by a communication channel. h) The implications of the emerging topic of cognition for radar will be considered for Adaptive RRM. i) Management of multiple sensors on a single platform. Methods for the intelligent coordination of these sensors will be explored.
