In order to detect a useful signal affected by noise, a measurement is taken of the expected S/N ratio of this signal over a time slice, a measurement of the estimated white noise alone is taken over another time slice without useful signal, the mean energy of the noise and of the noise-affected signal is calculated, in each of their time slices, the theoretical detection threshold is calculated, the ratio of these two energies is calculated, and the ratio is compared with the calculated threshold, this threshold being greater than 1 (ideal threshold).
