Disclosed is a method for measuring a distance between a distance sensor (5), which is carried on a vehicle, and an object (2). The method includes emitting electromagnetic impulse signals (6) and receiving signals (7), which are reflected by the object. Subsequently the signal propagation time is determined. Pulses (10) received after having been reflected by the object (2) are separated and added together, after which the mean value is formed, and the received pulses are superimposed with a modulation signal (18). Also disclosed is a device suited for carrying out the method.
