The invention provides a radar device. The radar arrangement has an antenna arrangement with a first set of antennas for establishing a first propagation channel and a second set of antennas for establishing a second propagation channel. A signal processing device of a radar device determines a first differential phase shift between first radar signals propagating via a first propagation channel and a second differential phase shift between second radar signals propagating via a second propagation channel. The first set of antennas is located at positions that generate a first differential phase shift for a first plurality of target angles, and the second set of antennas is located at positions that generate a second differential phase shift for a second plurality of target angles. The signal processing apparatus determines an angular position of the target object as a unique target angle that is part of the first plurality of target angles and the second plurality of target angles. 本公开提供雷达装置。雷达装置具有天线装置，该天线装置
