Abstract : This report describes the results obtained during the second year of a program of continuing research in the mathematical problems associated with the analysis and design of Air Force sensor correlation and data fusion systems. These systems play a vital role in the command and control process, but there presently exists no systematic and quantitative methodology for their analysis and design. In the first year of research, ALPHATECH investigated an important subproblem: the distributed detection problem associated with determining the presence or absence of targets from a collection of distributed sensors. In the second year of research, ALPHATECH has obtained novel, exact expressions for the probability density functions of the local log likelihood rations, and has used these expressions to generate an extensive set of design curves. In the third year of research, which is presently on-going, being investigated is another important class of problems, namely, sequential distributed detection problems. (Author)
