METHOD AND ARRANGEMENT FOR EVALUATING A DISTANCE BETWEEN AT LEAST TWO ANTENNA UNITS

A method for evaluating a distance between at least a first antenna unit and a second antenna unit by two-way transmission of at least two signals having different circular polarizations between the antenna units. Phase information is determined and used to determine at least a first phase sum and a...

Beschreibung
Zusammenfassung:	A method for evaluating a distance between at least a first antenna unit and a second antenna unit by two-way transmission of at least two signals having different circular polarizations between the antenna units. Phase information is determined and used to determine at least a first phase sum and a second phase sum, where the phase sums are further utilized in determination of at least one distance indicator that is indicative of the distance between the first antenna unit and the second antenna unit.
