Abstract:

An optimal statistical treatment algorithm, valid for wide and narrow band processes, is obtained for the detection of a weak harmonic signal on a Gaussian narrow band noise background. The integral is based on the statistics of intervals between intersections of zero level processes. It is shown that the noise rejection capacity of a detection process increases when the absolute signal mismatch level with respect to the central frequency of the noise spectrum increases.
