Evaluation of an Estimator for Real-Time Missile Tracking.
Abstract
The report contains an abbreviated evaluation of a Kalman filter designed to estimate in real time the position and velocity of a missile. Most aspects of the evaluation are rather cursory. However, the evaluation of the Automatic Source Selection feature of the estimator received detailed attention. Due to computational constraints, the information from only one radar can be processed at each time instant. The Automatic Source Selection feature selects the 'best' radar. The basic logic of the feature is sound; however, several recommendations for improvement are made. Included is a recommendation to use a weighted least squares combination of the individual radar Kalman filters. It is proven that the recommended least squares estimate will always be better than the single-radar Kalman filter estimate, even for the best estimate. (Author)
