CRITTENDON,RICHARD, DUBINSKY,ED · Defense Technical Information Center (DTIC) · 1961
Results are collected from various studies that were motivated by the problems associated with estimating ballistic trajectories from tracking data. Material is given in the following areas: discrete orthonormal polynomials; digital filtering based on the eigenvector of the noise correlation matrix; digital filters for smoothingA LINEAR TIME FUNCTION FROM EXPONENTIALLY CORRELATED NOISE; CRITERIA GUARANTEEING CONVERGENCE OF Newton's method in one variable and a modified Newton's method in several variables; and a new and unique, but apparently inapplicable, approach to the smoothing of tracking data.
