A method for locating an object in a plane that includes a first so-called learning phase for informing a database, and a second so-called location phase, the location phase using a classifier operating using the database comprising information representing the transmission of signals between the object and antennas, for determining a probability of location of the object in zones of the plane, the location phase further using a neural network, for determining, for the zone of the plane for which the location probability is the highest, the position of the object in the form of coordinates in the plane. The invention also relates to a location device implementing the method.
