Abstract
A radar system for a vehicle includes an antenna element installable at an outer shell of the vehicle, a dielectric waveguide, and a radar circuit configured to communicate with the antenna element via the dielectric waveguide. A vehicle includes a plurality of radar radio heads arranged at an outer shell of the vehicle, a plurality of waveguides, and a radar circuit configured to generate a common local oscillator signal and simultaneously provide respective radio frequency signal derived from the common local oscillator signal to the plurality of radar radio heads via the plurality of waveguides.

A radar system for a vehicle, comprising:
- a first antenna element and a second antenna element installable at an outer shell of the vehicle;
- a first dielectric waveguide and a second dielectric wave guide;
- and
- a radar circuit configured to simultaneously communicate with the first antenna element via the first dielectric waveguide and with the second antenna element via the second dielectric waveguide, and to generate phase coherently for a first and a second radio frequency signal, to provide the first radio frequency signal to the first antenna element via the first dielectric waveguide, and to provide the second radio frequency signal to the second antenna element via the second dielectric waveguide,
- wherein the first antenna element is configured to adjust a phase of the first radio frequency signal, and the second antenna element is configured to adjust a phase of the second radio frequency signal.
A vehicle, comprising:
- a plurality of radar radio heads arranged at an outer shell of the vehicle;
- a plurality of waveguides;
- and
- a radar circuit configured to generate a common local oscillator signal and simultaneously provide respective radio frequency signals derived from the common local oscillator signal to the plurality of radar radio heads via the plurality of waveguides, and to generate phase coherently for the radio frequency signals, wherein the radar radio heads are configured to adjust phases of the radio frequency signals.
