Development of Real-Time Error Ellipses as an Indicator of Kalman Filter Performance.
Abstract
An error ellipse plotting routine was developed to provide real-time indication of Kalman filter performance. The study included an evaluation of the Hewlett-Packard HP-86 computer system's capability for providing real-time tracking information and an evaluation of the computer's possible use on the three-dimensional underwater tracking range at the Naval Underwater Weapons Engineering Station, Keyport, Washington. A series of tracking runs were used to demonstrate both linear and extended Kalman filtering. Information obtained from the error ellipse was useful as a tool for indicating filter performance and for making decisions regarding filter parameter modification. The HP-86 provided accurate, reliable results and it could be used for on-line graphics. However, the computing speed of the HP-86 computer as used in this study was too slow for on-line processing of the three-dimensional tracking problem. (Author)
