Claim Text:
1. A method for distance measurement, the distance measurement being performed on the basis of transmitting, particularly electromagnetic, signals between at least two objects and measurements of phase angles at said at least two objects, wherein from each of said at least two objects several signals are being emitted and analyzed with reference to their phase angle, said signals being at least partially emitted at different frequencies, said method being performed in at least two stages, wherein in a first of the at least two stages at least one measurement with at least two emissions with a frequency difference between frequencies of successive emissions with frequencies that have not been used in this stage, at least not by the emitting object, is performed, said frequency differences being selected from a start-measurement frequency difference range and selection of a measurement-frequency difference range on the basis of such at least one measurement in said first stage, wherein in a second of said at least two stages at least one measurement with at least two emissions with a frequency difference between frequencies of successive emissions with frequencies that have not been used in this stage, at least not by the emitting object, is performed, wherein said frequency differences are selected from the selected measurement-frequency difference range.
