SENSITIVITY OF VARIOUS DETECTORS TO KNOWLEDGE OF SIGNAL AND NOISE PARAMETERS.

Abstract

This work is concerned with the problem of detecting a random signal in the presence of additive noise when the distributions of both signal and noise are known except for the values of some particular parameters. The approach used is based upon the use of signal 'shape' information; i.e., knowledge of the degree to which both the observed signal and noise energy tend to be concentrated, in order to determine decision rules that are useful, independent of the values actually assumed by the unknown parameters. To proceed quantitatively with this approach, a particular hypothesis testing problem is formulated in which N independent observations are made. Each observable is taken to be chi-square distributed with two degrees of freedom, but with a mean value that may be unknown both when the signal is present and when it is absent. (Author)
