Abstract

An electronic control device (3) controls the transmitter (1) and an electronic processing chain (13-20) treats the data detected. The electronic control device (3) transforms the data to be transmitted into an electric signal suitable for transmission. The signal is made up of a train of elementary signals each corresponding to a train formed from at least two identical pulses, the difference between the number of impulses of two trains corresponding to two different elementary signals being at least equal to two. The data processing chain (13-20) associated with the detector (12) eliminates the elementary signals formed from a single pulse.
