Maneuver tracking algorithms for AEW target tracking applications

In a previous paper, we described AEW advanced tracking algorithm development and showed performance results for straight line targets. In this paper we show modifications of the tracking and association algorithms necessary to track the remaining 100 maneuvering targets of the 120 targets scenario. As part of ongoing AEW advanced tracking algorithm development activities, a novel approach has been developed that utilizes the Unbiased Coordinate Conversion Filter developed by Bar-Shalom et al for range and azimuth angle processing from the radar with a standard EKF for rdot and angular measurements from other sensors identified as a combined Kalman filter. We also incorporated fading memory into the filter to make it responsive to target maneuvers.
