INVESTIGATIONS OF ADAPTIVE DETECTION TECHNIQUES.
Abstract
This interim report, which describes an investi gation of adaptive detection techniques, is or ganized into two fairly independent sections. Chapter II describes the situations under which use of an adaptive detection system may be desirable, the general characteristics of such systems and some results obtained by analog simulation of one system which has shown that the detection performance of the system improves as the system converges to a matched filter, as predicted by theory. Chapter III presents a detailed analysis of a one-dimensional nonpara metric system. By making simplifying assump tions, recursion formulas for the first and sec ond moments of the signal values are obtained for the case when the noise is gaussian condi tions under which these moments tend to certain limits (convergence) are obtained, and the limits, which turn out to be biased, are evaluated. Means for removing the bias are described. Ex perimental results, obtained by means of a digi tal computer, are found to agree fairly well with the approximate theory. (Author)
