Claim 0:
1. A method for detecting a time-of-flight signal, the method comprising:
transmitting a signal train through a medium, wherein the signal train comprises a sequence of waves of a first group and of a second group, wherein the first and second groups are shifted in a time domain according to a predetermined phase shift, and wherein the phase shift is inserted between the first group and the second group such that the first group of waves is transmitted earlier in time than the second group of waves;
receiving the signal train as a received signal train and as a function of time;
detecting a phase shift in the received signal train;
assigning wave periods of the received signal train to respective wave periods of the first group using the detected phase shift as a reference; and
determining a sequence of time-of-flight signals from the sequence of waves of the first group and the assigned wave periods of the received signal train, respectively.
