Abstract: A vehicular radar sensing system includes a radar sensor that includes a radiation slot sheet, a wave port sheet, and a waveguide sheet sandwiched between the radiation slot sheet and the wave port sheet. The sheets are joined together. The radiation slot sheet includes at least one transmitter that transmits radio signals and at least one receiver that receives radio signals. The waveguide sheet guides the transmitted radio signals from the radiation slot sheet to the wave port sheet and guides reflected radio signals from the wave port sheet to the radiation slot sheet. The transmitted radio signals are provided to the environment via at least one wave port of the wave point sheet. The reflected radio signals are received from the environment at the at least one wave port.

Abstract: A vehicular radar sensing system includes a radar sensor disposed with a field of sensing within an interior of a vehicle. The radar sensor includes a plurality of transmitters and a plurality of receivers and a printed circuit board (PCB) having electronic circuitry and associated software. The electronic circuitry includes a processor operable to process outputs of the receivers. The plurality of transmitters includes a plurality of transmitting antennas, and the plurality of receivers includes a plurality of receiving antennas. The plurality of transmitting antennas is established on a surface of a glass panel of the vehicle in a transmitting antenna pattern. The plurality of receiving antennas is established on the surface of the glass panel in a receiving antenna pattern. The vehicular radar sensing system, responsive to processing of outputs of the plurality of receivers, detects presence of an occupant within the cabin of the vehicle.
