A receiver exploits unique higher order statistics of temporally dependent waveforms to classify, characterize, identify (fingerprint) and intercept a waveform within the field of view of the receiver. The method uses 4th-order non zero lag auto cumulants of the received waveform and 4th-order non zero lag auto cumulants of known waveforms to classify and characterize the signal. The receiver includes a multi~element array and does not need a priori knowledge of the transmitted signal source obtain a fingerprint.

Un récepteur met en valeur uniquement des statistiques d'ordre supérieur de formes d'ondes temporairement dépendantes pour classer, caractériser, identifier (empreintes digitales) et intercepter une forme d'ondes à l'intérieur du champ de vision du récepteur. Un procédé utilise des valeurs auto-cumulées à pas différent de zéro et de quatrième ordre de la forme d'onde reçue et des valeurs auto-cumulées à pas différent de zéro et de quatrième ordre de formes d'ondes connues pour classer et caractériser le signal. Le récepteur, qui comporte un réseau à éléments multiples, n'a pas besoin de connaître a priori la source de signaux transmis pour obtenir une empreinte digitale.
