Abstract: An antenna array system includes a receiver with a plurality of receiving chains adapted to receive incoming signals from corresponding receiver antennas. A respective directional coupler is positioned in proximity to each of the plurality of receiving chains. The plurality of receiving chains is adapted to receive a respective pilot signal through the respective directional coupler, the respective pilot signal being transmitted simultaneously. A controller has a processor and tangible, non-transitory memory on which instructions are recorded for a method of calibration. One of the plurality of receiving chains is selected as a reference channel. The controller is adapted to perform calibration for the plurality of receiving chains based on the respective pilot signal, including obtaining respective chain phase values and respective gain factors. The calibration is performed without mechanical switching off or physically disconnecting the corresponding receiver antennas.

Abstract: A vehicle, radar system for the vehicle and method for detecting an object. The radar system includes a transmitter, a receiver and a processor. The transmitter is configured to generate elliptically-polarized signals having a transmission polarization sense. The receiver configured to be receptive to signals having a reception polarization sense opposite the transmission polarization sense, thereby filtering multiply-reflected signals. The processor operates the transmitter to generate a source signal and operates the receiver to receive a reflection of the source signal from the object. The processor detects the object from the received reflection.

Abstract: A vehicle, radar system and a method of detecting an object. The radar system includes a transmitter, a receiver and a processor. The transmitter generates a transmitted signal having a non-linear polarization. The receiver receives a received signal that is a reflection of the transmitted signal from the object. The processor adjusts a phase of the transmitted signal at the transmitter to obtain a selected power of the received signal at the receiver.
