Patent ID: 7995190

Claim:
A method for measuring a distance between a distance sensor ( 5 ), which is carried by a vehicle ( 1 ), and an object ( 2 ), the method comprising: emitting electromagnetic impulse signals ( 6 ); and receiving signals ( 7 ) which are reflected by the object ( 2 ), wherein the signal ( 7 ) which is reflected by the object ( 2 ) comprises a related sequence of pulses ( 10 ), each pulse ( 10 ) being separated in order to attain a sensed pulse ( 14 ), and the sensed pulses ( 14 ) and added together and a modulation signal ( 18 ) is superimposed onto the received pulses ( 10 ) prior to separation and addition wherein the modulation signal ( 18 ) comprises a related sequence of pulses ( 10 ) of constant amplitude distribution, wherein the modulation signal ( 18 ) is distributed uniformly in terms of time, and its amplitude corresponds to a quantization level ( 13 ) during separation of the received pulses, or to an integral multiple of such a quantization level.
