Cognitive Radar Tracking with Adaptation of Update Interval and Integration Time

ESA (Electronically Scanned Array) radars can simultaneously carry out many tasks. Since the radar scheduler has limited time resources, the radar time usage of each task must be limited while still achieving acceptable performance. In this paper we have further developed and by simulations studied a method from the literature for adapting the update interval and the integration time, which together determine the radar time usage, for tracking a single target. The method has properties common in “cognitive radar”. The adaptation works and gives a better performance than fix update interval and integration time but it has some problems.
