A different way to detect maneuvers in Kalman-filter-based target tracking is discussed. By examining the behavior of the Kalman gains, a target maneuver may be detected prior to the state change being detected. A first look at this approach is presented. The individual Kalman gains of the target tracking algorithm are monitored over time. Variations in the gains' behaviors such as zero crossings...
An image correlation technique for target data association is augmented to incorporate track and measurement uncertainties. In this development, the uncertainty of target representations is assumed to be represented by a Gaussian distribution. The new approach uses fuzzy logic to simplify the mapping of the uncertainty to a usable construct to adjust the image generation based on the uncertainty of...
Target registration can be considered a problem in aligning the reports of two sensor platforms. It is often a result of sensor misalignment and navigation errors. One technique to alleviate these errors is to continually recompute a correction with each report. In this paper, a different approach using a modification of an adaptive neural network technique is proposed and developed. The technique,...
