Abstract
Cette invention se rapporte à un procédé utilisant un récepteur agile en fréquqence dans un système radio agile en fréquence pour recevoir des signaux provenant d'un émetteur émettant des messages d'information sur plusieurs fréquences pseudo-aléatoires. Ce procédé consiste: à balayer un spectre radio disponible (517, 518); à mesurer (515) dans une partie de ce spectre radio disponible au moins l'une des valeurs suivantes, l'intensité du signal, le seuil de sensibilité et la qualité de verrouillage du signal, fournies par une sortie dudit récepteur agile en fréquence; à identifier la partie du spectre radio disponible ne parvenant pas à assurer une réception correctement codée (508); à produire, sur la base de cette mesure effectuée et d'autres indications du système, une prévision d'un niveau de puissance de signal indésirée, dans la partie du spectre radio disponible, pouvant apparaître lors d'un balayage ultérieur par le récepteur agile en fréquence; et à stocker (505) ladite prévision dans un emplacement de mémoire associé à cette partie du spectre radio disponible.
