Studies in Aerospace Vehicle Detection and Defense.
Abstract
The report describes the investigation and development of new concepts and techniques in the areas of control systems, optimal tracking, and signal processing, particularly as they apply to navigation and guidance of space vehicles. Four separate problems have been explored. The first problem concerns the design of otpimal trajectories for parameter estimation. Particular emphasis is placed on the optimal utilization of a priori information and on problems involving multiple parameters. The second problem concerns the estimation of signal to noise ratio in communication systems. Implementation of both maximum liklihood and least squares esimators is discussed and the results of a simulation of a simple SNR measurement device are described. The third problem describes the design of a gneralized feedback controller which, in addition to determining the optimal control strategy, determines the optimal number and scheduling of observations. The fourth problem concerns the optimal filtering of tracking observations under conditions in which spurious measurements may be present. (Author)
