Abstract (en)
[origin: EP0518742A1] In order to detect a noisy wanted signal, a measurement of the expected S/N ratio of this signal is taken over one time slice, a measurement of the estimated white noise alone is taken over another time slice without wanted signal, the mean energy of the noise and of the noisy signal are calculated, each in its time slice, the theoretical detection threshold and the ratio of these two energies are calculated, and the ratio is compared with the calculated threshold, this threshold being greater than 1 (ideal threshold).
