<p>The invention relates to a method for detecting the position of a wavefront indicating the occurrence of a researched event in a time signal received by a detector, wherein: digitizing the signal received by the detector in order to a obtain a work signal; filtering the work signal N4 times with a band pass filter in order to obtain N4 filtered work signals having different pass bands; processing the N4 filtered work signals according to a peak detection method for detecting for each signal the position of a first wavefront in terms of arrival time; placing, in a frame of reference, N4 points having an ordinate representing one of the arrival times and an abscissa representing the width of the associated band; searching an exponential asymptote extending through a maximum of the N4 points, the position of the wavefront being the ordinate of a point on or practically on the asymptote and having the maximum abscissa.</p> |
