Abstract
A method for detecting series of substantially periodic bursts of substantially sinusoidal signals, in particular, but not exclusively, series of bursts of signals transmitted recurrently (by pingers for example), this method making it possible to ensure the quick and reliable detection of such signals in the presence of significant interference noise. This method includes slightly delayed processing of received signals, spectral analysis and time integration, and presentation of the results in the form of a two-dimensional image of the successive recurrences of the bursts according to time slots of the received signals.
