Abstract: A method for localizing an object, including the acts of: transmission of a first signal by a first transmitter assigned to the object and of a second signal by at least one second transmitter; reception of the first and of the second signal by at least three receivers; in each receiver and for the first and the second signal: a) generation of a first and of a second reference signal; b) correlation between the first signal and the first reference signal and between the second signal and the second reference signal; c) interpolation of samples resulting from the correlation; d) deduction of the propagation time of the first and of the second signal; e) calculation of the difference between the propagation times of the first and of the second signal; and, by triangulation, deduction of the position of the object.
