1. A method for locating an object in a plane, the object transmitting radio signals to a plurality of reception antennas positioned in the plane, the reception antennas each being combined with a reception device configured to deliver at least one item of information representing the transmission of said signals from the object to said antenna, the method comprising:
i) dividing the space into zones each comprising only one of the reception antennas,
ii) recording, in a database, for each position among a plurality of known positions of the object in the plane, the at least one item of information representing the transmission of said signals from the object to each of the antennas, the position of the object in the form of coordinates in the plane, and an identifier of the zone,
iii) training a neural network to determine a location of an object in each of the zones of the plane, from the information recorded in the database,
iv) receiving radio signals from the object and through the plurality of antennas, and defining at least one item of information representing the transmission of signals from the object to each of the antennas,
v) determining, by a classifier, from all the information representing the transmission of the signals between the object and each antenna, a probability of location of the object in each of the zones of the plane,
vi) determining, by the neural network, for the zone for which the probability of location is the highest, the position of the object in the form of coordinates in the plane,
wherein the division of the plane into zones is performed using a discrete set of points defined in the plane by the respective positions of the reception antennas.
