    Abstract: A three-dimensional (3D) antenna array system in the form of a phased array antenna having a first antenna array and a second antenna array, a calibration circuit including an external signal generator, and a hinged power transformer is described. The external signal generator is electrically connected to the first antenna array, and the first antenna array is electrically coupled to the second antenna array via the hinged power transformer. The hinged power transformer mechanically joins the first antenna array to the second antenna array in one of a first position and a second position, with the first antenna array being disposed at an angle in relation to the second antenna array when the hinged power transformer is disposed in the first position.

    Abstract: A system and associated method for calibrating a radar system is described, wherein the radar system includes a phased array antenna including a first antenna array and a second antenna array, a transmitter array, and a receiver array, communication leads, a calibration circuit, and a controller. The calibration circuit includes a power divider and directional couplers. A pilot signal is injected, via the power divider and the directional couplers, to the receivers during a quiet period. Phase offsets and gain imbalances for the receivers are determined in relation to a reference channel based upon the pilot signal, and phase calibrations and gain calibrations for the receivers are determined based upon the phase offsets and the gain imbalances, and a radar-related parameter is based upon the phase calibrations and the gain calibrations for the receivers.

    Abstract: A multi-directional viewing camera system for a motor vehicle including a vehicle body defining an interior compartment and a body panel having an exterior surface and an interior surface facing the interior compartment. The camera system includes a mirror module for mounting to the body panel exterior surface. The mirror module is configured to capture and transmit incident light from at least one field of view (FOV) and has a polarizing beam splitter configured to reflect an s-polarized component and transmit a p-polarized component of the incident light in a visible spectral range. The camera system also includes a camera module having a video camera for mounting to the body panel interior surface. The camera module is configured to receive from the mirror module the s-polarized or the p-polarized component of the incident light and selectively display at least one FOV within the interior compartment.

    Abstract: A vehicle, radar system for a vehicle and a method of detecting a parameter of an object is disclosed. The radar system includes a base radar and a frequency converter. The base radar generates a first frequency source signal within a first frequency range and is receptive to a first frequency reflected signal within the first frequency range. The base radar is configured to determine a parameter of an object from the first frequency reflected signal. The frequency converter is configured to convert the first frequency source signal to a second frequency source signal within a second frequency range and to convert a second frequency reflected signal within the second frequency range to the first frequency reflected signal.
