Abstract
A military radar or radio communication system comprises, in particular, mobile transmitter-receiver apparatus wherein a plurality of operating frequencies are constantly changed in accordance with a frequency hopping schedule. The system is particularly characterized in that the transmitter, during such time intervals in which it is not used for the purpose of useful signal transmission, for example during pauses in speech is utilized for interference on frequencies for partial frequency ranges not required at that time for the purpose of useful signal transmission, and that, to this end, a corresponding transfer installation, preferably pre-programmed or remotely controlled by a central station, is provided in the transmitter.
