Estimation Theory Basic to Navigation and Guidance System Design.
Abstract
The research program consisted of two parts, parallel and pipeline synthesis of nonlinear filters and a priori bounds for the mean square error of nonlinear filters. It was noted very early in the program that the choice of computational realization device could produce dramatic changes in estimate production speed, especially parallel and pipeline devices. Specific programs were tailored to three difference computers to realize the nonlinear filter and take full advantage of the problem's parallel structure for each machine. The speed of estimate production was increased by a factor of 140. The second area concerned finding performance bounds on the error variance of the nonlinear filter for a specific problem, the cubic sensor. Using sensor orbit estimators and nonlinear functions of such estimates, rather effective bounds were discovered. (Author)
