Claim Text:
1. A system for radio frequency tagging a transmitter of a useful first signal S u , by a tagging second signal C tag comprising parameterizable time and frequency characteristics, said tagging second signal is transmitted simultaneously accompanying the useful first signal S u , said transmitter operating in a communication system or network, in a system comprising a number of users authorized and adapted to recognize the tagging second signal through specific processing operations, said system comprising at least the following elements: the transmitter configured to produce the useful first signal S a carrier of the tagging second signal C a band B an amplitude A time characteristics of the tagging second signal C modulation characteristics of the tagging second signal C a duration and a repetition period, T a description of a construction over the repetition period T a transmission antenna configured to simultaneously transmit said useful first signal S a receiver configured to receive and to process the useful first signal and the tagging second signal, and further configured to detect and to discriminate the tagging second signal from the useful first signal.
