Abstract
L'invention concerne un système télémétrique comprenant un circuit monostable numérique. Elle se rapporte à un système télémétrique dont le circuit monostable numérique comprend un basculeur D 122 et un registre 100 à décalage. L'appareil télémétrique est sensible avec précision aux signaux de plusieurs cibles, sans aucune limitation d'espacement minimal entre les cibles successives. L'appareil peut déterminer la distance de la cible dont le signal a été reçu en premier ou en dernier dans une fenêtre de distance. Application aux systèmes télémétriques.
