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.Military system for transmitting information by radio or radar with, in particular, mobile transceiver apparatus in which several working frequencies are continuously replaced by each other according to a frequency hopping process. During time slots where there is no transmission of information, for example during pauses in oral communication, the transmitter is used to interfere with frequencies or partial frequency ranges not used at this time to the transmission of useful signals.
