摘要： The present invention relates to a method (50) for detecting a plurality of useful signals in a total signal. Said useful signals correspond to radioelectrical signals emitted by different terminals in a multiplexing frequency band. Said method comprises steps for: - calculating (51) a plurality of spectrograms that have a compensated linear frequency drift and are respectively associated with different linear frequency drift values; and for each analysis frequency and each spectrogram, - performing time envelope filtering (52) of the values at the different times for analyzing said spectrogram at said analysis frequency by means of a filter representing a reference time envelope of the useful signals. A useful signal is detected at an analysis time and at an analysis frequency if a predefined detection criterion is verified by the value from a spectrogram resulting from filtering, that is, a so-called "filtered spectrogram," for said analysis time and said analysis frequency.
