Abstract:
1. A method of identifying a source of a signal wherein said signal is recorded and then analyzed in order to determine its spectrum, said method comprising the steps of: in parallel with recording said signal, storing parameters significant of the conditions under which said recording is made; after analyzing said signal and determining its spectrum, detecting lines emerging from the background noise of said signal, using a predetermined emergence threshold, comparing each line detected with some or all of a set of signatures of sources identified and inventoried in a database established prior to said recording; for each line detected, and where applicable, selecting signatures that may correspond to said detected line and, as a function of the resulting signature/line pairs, consolidating, resolving ambiguity of, or quantifying the source corresponding to said line; and said signature/line pair being consolidated, where applicable, if only one signature is selected for said detected line, by the following steps: the resolving of ambiguity corresponding to a plurality of signatures being selected for a line and/or the same signature being selected for more than one line, and comprising the following steps: said source corresponding to a line being quantified if no signature is selected for said line by the following steps:
