Abstract

Système militaire de transmission d'informations par radio ou radar avec, en particulier, des appareils émetteurs-récepteurs mobiles dans lesquels plusieurs fréquences de travail sont continuellement remplacées l'une par l'autre selon un procédé à sauts de fréquence. Durant les créneaux de temps ou il n'y a pas transmission d'informations, par exemple durant les pauses de communication orale, l'émetteur est utilisé pour faire du brouillage sur les fréquences ou les plages de fréquence partielles non utilisées à ce moment pour la transmission des signaux utiles.
