Track quality to track error covariance

摘要

A computer-implemented method for estimating track error covariance of a sensor track data in a Link 16 tactical data link network from track quality involves receiving at a computer system the sensor track data on a ballistic target including the track quality and by estimating the track maturity, the position and velocity error covariance eigenvalues (λ_p, λ_v), and the position and velocity error covariances (C_p, C_v), the track error covariance of the sensor track data is calculated. The resulting error covariance is provided to the weapons control systems for more accurate engagement of the ballistic targets.
