Reducing the probability of target loss in an automatic tracking system
Abstract
Tracking by correlational signal processing is analyzed in order to compare the tracking loss probabilities due to random fluctuations of target motion for tracking with and without the use of an extrapolator. Target parameters were chosen which are typical of a jet transport aircraft reacting to random forces as a first order inertial object. The target maneuvering statistic which is most unfavorable for tracking is considered, and target loss probability is calculated for a system without extrapolator and one with a two-point extrapolator. The scheme with extrapolator is seen to be superior to the one without it.
