1. A device comprising:
an antenna device comprising a first set of antennas configured to establish first propagation channels, a second set of antennas configured to establish second propagation channels, and a third set of antennas configured to establish third propagation channels; and
a signal processing device configured to determine a first differential phase shift among first radar signals propagating via the first propagation channels and to determine a second differential phase shift among second radar signals propagating via the second propagation channels,
antennas of the first set of antennas located at positions configured to generate the first differential phase shift for a first multitude of target angles, and antennas of the second set of antennas located at positions configured to generate the second differential phase shift for a second multitude of target angles,
the signal processing device configured to evaluate third radar signals propagating via the third propagation channels established by the third set of antennas and to determine a third multitude of target angles from the third radar signals, and
the signal processing device configured to determine an angular position of a target object as a unique target angle by selecting an angle that is common between the first multitude of target angles, the second multitude of target angles, and the third multitude of target angles.
