Method and device for correlating a signal, in particular an ultra wideband signal

摘要

The waveform of the signal varies according to the distance at which the signal was emitted, and several correlation signals are defined and correspond respectively to at least part of several sampled waveforms of the signal respectively emitted at several distances of different values so that the sum of the maxima of intercorrelations performed respectively between the various correlation signals and the various sampled waveforms is substantially constant over an interval including all the values of the distances. The correlation processing includes several elementary correlation processings respectively performed with the correlation signals and each delivering initial correlation values, as well as a summation of the homologous initial correlation values respectively delivered by the elementary correlation processings so as to obtain the correlation values.
