Abstract : The theory of least mean squared error curve fitting is used to derive expressions for the accuracy with which the cutoff position and velocity of a ballistic missile can be estimated from noisy measurements. The correlation between the estimates is determined. These results are then specialized to the estimation of angular position and velocity from measurements made with an infrared tracker. Numerical examples for two possible trackers are presented. (Author)
