Abstract

A system and method for determining the relative position of stations through radio location is proposed. In one aspect, a station is configured as an apparatus having at least one antenna. At least one first station has at least one first antenna, and at least one second station has at least two base-modulated antennas. The first station sends at least one locating signal via the first antenna. The second station reflects the locating signal as a first modulated reflected locating signal via a first base-modulated antenna and as a second modulated reflected locating signal via a second base-modulated antenna. The first station receives the modulated reflected locating signals via the antenna. The phase relationships of the received modulated reflected locating signals are used to ascertain at least one position angle for the relative position between the first station and the second station.
