Abstract: A method for operating an angle resolving radar device for automotive applications comprises: routing at least a first and second antenna signal between a radar circuit and an antenna device, wherein the first and second antenna signals are routed via a common signal port of the radar circuit; transducing between the first antenna signal and a first radiation field, the first radiation field having a first phase center, and between the second antenna signal and a second radiation field, the second radiation field having a second phase center, wherein a location of the second phase center is shifted with respect to a location of the first phase center; constructing at least one angle resolving virtual antenna array using the location of the first phase center as a first antenna position and the location of the second phase center of the second radiation field as a second antenna position.

Abstract: A radar device, for example for automotive applications, comprises a radar circuit, an antenna device and a signal processing device, wherein the radar circuit is configured to transceive a first antenna signal and a second antenna signal, wherein the first antenna signal occupies a first frequency band and the second antenna signal occupies a second frequency band that is separate from the first frequency band, wherein the antenna device is configured to transduce the first antenna signal via a first antenna of the antenna device and the second antenna signal via a second antenna of the antenna device, and wherein the signal processing device comprises a ranging module that is configured to jointly process the first and second antenna signal to determine a distance to a target object irradiated by the antenna device.
