Abstract
A frequency division, energy comparison, source detection signal processing system which decomposes a wide-band signal into a plurality of narrow frequency band components, generates the energy envelope of each of those narrow band components, determines the envelope correlation coefficients, and detects the presence of a source contributing to the wide-band signal from the correlation coefficients.
