Abstract
Selon certains modes de réalisation, un procédé mis en œuvre par un récepteur radio comprend les étapes suivantes : recevoir une pluralité d'échantillons de signaux radio ; calculer une première fonction de logarithme de vraisemblance pour une première hypothèse stipulant que la pluralité d'échantillons de signaux radio ne comprend que du bruit de fond ; calculer une seconde fonction de logarithme de vraisemblance pour une seconde hypothèse stipulant que la pluralité d'échantillons de signaux radio comprend une impulsion radio d'une largeur et d'un temps de démarrage particuliers ; estimer des paramètres pour la première fonction de logarithme de vraisemblance et la seconde fonction de logarithme de vraisemblance ; et sur la base de la première fonction de logarithme de vraisemblance, la seconde fonction de logarithme de vraisemblance et les paramètres estimés, calculer une mesure de logarithme du rapport de vraisemblance qui minimise une probabilité de détection manquée pour une probabilité de fausse alarme cible ou qui réduit au minimum une probabilité de fausse alarme pour une probabilité de détection manquée cible. Le procédé consiste en outre à comparer la mesure de logarithme du rapport de vraisemblance à une valeur seuil et à déterminer la présence d'une impulsion radio.
