A proximity sensor (1) for a parking area designed to detect the presence of an obstacle constituted by a parked vehicle and comprising a transmitting radar (3), designed to send electromagnetic pulses (Ir) towards the obstacle (4), a receiving radar (5), designed to receive the pulses reflected by the obstacle (4), and a processing circuit (22), designed to compare samples detected in a certain condition of absence of an obstacle (4) in a calibration step with those detected in a condition of detection of an obstacle (4) to determine the presence/absence of the obstacle (4). |
