A Comparative Study of Fire Control Target State Estimators.

Abstract

Application of the Kalman Filter to the fire control problem is considered. While the theory and practice in this field are well developed, conflicting claims have been made regarding the relative advantages of statistical decoupling in fixed inertial coordinates as compared to rotating non-inertial coordinates. An error analysis model, consisting of a sub-optimal filter and truth model, shows the error added, in each of three formulations, due to several sub-optimal approximations. Plots, including error ellipses, help to provide an intuitive feel for the results of decoupling. (Author)
