A Determination of the First Two Moments of the Ale Output Detector.

Abstract

This report deals with a computation of the first two moments of the output distribution of the adaptive line enhancer (ALE) detector. Its primary motivation is to provide a means of determining the detection characteristics of the integrated spectral output. Previous results have relied on assumptions regarding the output statistics themselves; i.e., that they be chi-square distributions. In this work, only two assumptions are made: that the input to the detector be a sinusoid in white Gaussian noise and that the discrete Fourier transform (DFT) length and ALE filter length be considerably smaller than tau, the adaptive time constant of the ALE filter.
