Abstract

A fully adaptive radar framework for tracking applications has been proposed in recent work, where the claim is that adaptation using feedback between transmitter and receiver could improve tracker performance. The update rate is an important parameter in a multi-target tracking system since it both controls the resource usage in an electronically steered antenna radar system, and the tracking error is directly dependent on the update interval of the track. For maneuvering targets, the track update interval affects the risk of losing track. This seminar presents a cost function developed to balance the radar resource usage with the track error. The method is illustrated with simulated examples to show how the radar could operate in different scenarios. 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.

Bio

Jonas M. Christiansen received his M.Sc. degree in Engineering Cybernetics from the Norwegian University of Science and Technology (NTNU) in 2009, and subsequently, Jonas started working at the Norwegian defense research establishment (FFI). Jonas key interests have been the field of surveillance radar systems, passive bistatic radar, and signal processing, and is currently working toward a Ph.D. in the cognitive radar sensing group at Ohio State University.
