摘要： The present application discloses embodiments that relate to a radar system. The embodiments may include a plurality of radiating waveguides each having a waveguide input. The embodiments also include an attenuation component, which can be located on a circuit board. The embodiments further include a beamforming network. The beamforming network includes a beamforming network input. The beamforming network also includes a plurality of beamforming network outputs, where each beamforming network output is coupled to one of the waveguide inputs. Additionally, the beamforming network includes a coupling port, wherein the coupling port is configured to couple at least one waveguide of the system to a component external to the waveguide.
