Abstract (en)

[origin: WO2013050597A1] The invention relates to a method for determining the angle (alpha+beta) between a first component (10) and a second component (20) which moves relative to the first component, particularly of an installation comprising said first (10) and second component (20), a radar sensor (30) being used that has at least two channels (40) each arranged to be spatially at a distance from the another and motion-coupled to the first component, and at least two coding radar targets (60) being used each of which is arranged to be spatially at a distance from the other and motion-coupled to the second component (20). In said method, a signal (TX) is sent to each of the radar targets (60) using one of the at least two channels (40) of the radar sensor in each case, at least one coded signal (RX) being sent by these radar targets (60) respectively upon or after receiving such a signal (TX), one of the at least two coded signals (RX) being received by one or more channels (40) of the radar sensor in each case, and the temporal relationship between at least two of the received coded signals (RX) being acquired and used to determine the angle (alpha+beta).
