Abstract: A method for measuring a distance separating a vehicle and an identifier is disclosed. The method includes transmitting, from the vehicle to the identifier, a first train of first sinusoidal signals, receiving, by the identifier, an image train of second sinusoidal signals corresponding to the first sinusoidal signals, generating, by the identifier, measurements of phases and amplitudes of the second sinusoidal signals that are altered from the first sinusoidal signals by transmission from the vehicle to the identifier, constructing a frequency spectrum based on the measurements and a second image train received by the vehicle from the identifier, where the frequency spectrum is constructed by detecting spectral lines of the first image train and the second image train, performing an inverse Fourier transform of the frequency spectrum to obtain a temporal signature, and calculating the distance on the basis of an intermediate time associated with a maximum of the temporal signature.
