Abstract

Automation & Control Systems Science & Technology Technology
This paper considers the Kalman, H-infinity, and H-2 continuous time, steady state, target tracking problem. The target escape criterion is examined, in particular, the probability that the position estimate will sufficiently degrade, causing the target to be outside the radar beam width. Analytical expressions for the probability of target escape are developed not only to compare the performance of the various filters, but also as a design tool to meet tracking specifications. It is shown that the Kalman and H-2 trackers have a lower probability of escape than the H-infinity tracker when the target maneuverability is Gaussian and within the tracker design setting. Conversely the H-infinity process generally has a lower probability of escape than the Kalman and H-2 trackers when the target maneuverability is a pulse acceleration.
