Abstract: A detection device includes an antenna for receiving an incident signal, and for delivering a base signal. A comparator receives the base signal and provides an intermediate signal representative of the sign of the base signal relative to a reference signal. A sampling circuit samples the intermediate signal for providing a digital signal. A digital processing circuit correlates the digital signal with a predetermined correlation signal.
