Fully adaptive radar for track update-interval control

Abstract

A fully adaptive radar framework has been proposed in recent publications, and this paper will implement the framework in an adaptive update rate application for a tracking radar. A cost function is developed to balance the radar resource usage with the track error. The method is illustrated with a simulated example to show how the radar could operate in a simple scenario. Using a cognitive radar experimental testbed, a similar scenario to the simulation is tested to show how a cognitive radar acts in a real world environment. The method enables the radar to operate using minimum resources when the target acts predictably. Conversely, the resource usage increases when the target maneuvers or track error increases.
