A Program of Research on the Applications of Adaptive Systems and Statistical Decision Theory to the Problems Involved in the Detection of Enemy Operations

摘要

This report summarizes the research performed on two problems: (1) to create and investigate models for the entire search, detection, and decision system, useful for determining the operating conditions for overall system optimality; (2) to investigate the statistical and probabilistic problems associated with TV bandwidth reduction studies. Part I reports on several models of search and detection in which detection stations are fixed and the objects sought are free to move about. Consideration is particularly given to the nature of the noise field in which the system operates. The problem considered is where to place detection stations and how to process the incoming signal for one station alone and for the system as a whole. The nature of the mathematical difficulties encountered in reaching a solution to this problem is presented. Studies reported on problem (2) include a mathematical algorithm for computing the area size distribution for points randomly illuminated on the TV screen, a comparison of the statistical properties of various masking techniques that may be applied in raster scanning, and an analysis of the motion of the center of illumination of the TV screen.
