Abstract

In an installation including first and second components, a radar sensor that has at least two channels, each arranged to be spatially at a distance from the other, is motion-coupled to the first component, and at least two coding radar targets, each arranged to be spatially at a distance from an adjacent target, are motion-coupled to the second component. A signal is sent to each of the radar targets using one of the at least two channels of the radar sensor. At least one coded signal is respectively sent by the radar targets upon or after receiving such a signal, one of the at least two coded signals being received by one or more channels of the radar sensor from each target. The temporal relationship between at least two of the received coded signals is acquired and used to determine an angle between the first and second components.
