A SONAD (110) control system (100) detects a received signal strength (RSSI) for a radio frequency (RF) signal (102), selects a threshold transfer function (400-404) in response thereto, generates a threshold control signal in response to the transfer function, and utilizes the threshold control signal to select the SONAD threshold value. During operation, the control system (100) decreases the attenuation of background noise levels for weak RF signals.
Un système de commande (100) de SONAD (110) détecte une intensité de signal (RSSI) d'un signal RF (102), sélectionne en conséquence une fonction de transfert de seuil (400-404), génère un signal de commande de seuil en réponse à la fonction de transfert et utilise le signal de commande de seuil pour sélectionner la valeur de seuil de SONAD. En fonctionnement, le système de commande (100) diminue l'atténuation des niveaux de bruit de fond pour les signaux RF faibles.
