The invention relates to a system and a method for locating at least one target using au array of transceivers or sensors, in which at least a portion has a known geographic location, each comprising data processing means implementing at least one algorithm for locating a target, means for transmitting/receiving a signal that decreases with the distance, the sensor array covering at least one geographic area or area, characterized in that they implement for each instant (t) an exchange of data or similarity data between the sensors and a leading sensor, and a distribution determination of the probability of the location of the target using at least one reession algorithm on the basis of the similarity data.
