<p>A system and method for radio frequency tagging a transmitter of a useful first signal Su, by a tagging second signal Ctag, the signals are transmitted simultaneously, comprises at least the following elements: signal generation means adapted: to produce a useful signal Su in a given frequency band B, at a frequency fSu and an amplitude ASu, and to determine, from the values of the band parameter BSu of the useful signal Su and from the amplitude ASu of the useful signal Su, the parameters of the tagging signal Ctag, a transmission antenna adapted to simultaneously transmit said signal Su and said tagging signal, the level of which is X dB lower than the useful signal Su, means for receiving and processing the useful signal and the tagging signal adapted to discriminate the tagging signal from the useful signal.</p> |
