摘要： The invention concerns a method for sorting an acoustic signal (S) or a spectral line (F) of maximal energy E, transmitted by a 'target', capable of being immersed in the sea, among a multitude of acoustic signals coming from particular noise generators (W), radiating acoustic signals of similar type and of energy higher than energy E, using: a set of N acoustic sensors, identically parametrized in standby mode, capable of being immersed, for detecting the presence of a signal (S) or a desired spectral line (F), the set of N sensors defining a particular number of standby cells to two adjacent sensors, each sensor being associated with one or several detection/target domains, which are defined as the geographical zones inside which the presence of the 'target' is known to be detectable and outside which the 'target' is known to be undetectable.; a maximum number Nmax of sensors concerning one or several 'set' zone(s) (selected among a set of elementary geographical zones) of a common standby cell and capable of simultaneously detecting the 'target'. The invention is characterised in that the acoustic signal (S) or the line (F) is detected by a number Nd of acoustic sensors in the set of N sensors, and analysed by a series of steps whereof the main ones comprise the definition of the noise generator (W) locating conditions and the determination relative to the set zones.
