Comparison of Three Extended Kalman Filters for Air-to-Air Tracking.

Abstract

The performances of the extended Kalman filter implementations for three different target acceleration models that estimate target position, velocity, and acceleration states for air-to-air gunnery were compared. The models included (1) a first order zero-mean Gauss-Markov relative target acceleration model, (2) a first order zero-mean Gauss-Markov total target acceleration, and (3) a constant turn rate target acceleration model. Measurements available to the extended Kalman filter at update were the range, range rate, and the error angles between the true line of sight and the estimated line of sight. Additional evaluations of the effect of variations in the length of the sample period and the effect of variations in the variances of the measurement noises were conducted for the extended Kalman filter using the constant turn rate target acceleration model. All evaluations were accomplished using Monte Carlo simulation techniques. (Author)
