Vers une Carte d'Identité Spectrale

Abstract : This paper studies a new spectral analysis strategy for detecting, characterizing and classifying the different “spectral structures” of an unknown stationary process. A “spectral structure” is defined as a sinusoidal wave, a narrow band signal or a noise peak. The spectral analysis strategy is based on the use of several successive and complementary spectral analyses. Then, the proposed methodology provides a way to calculate a “spectral identity card” of each spectral structure, similarly to a real I.D. card. This I.D. card including all information related to this structure results from the fusion of intermediate cards, which are obtained from different spectral analysis algorithms. The I.D. card permits the classification of the detected spectral structure into one of the following four classes: Pure Frequency, Narrow Band, Alarm and Reject.
