Abstract: A method and system to obtain a velocity measurement of a target detected by a radar system using an asymmetric Doppler spectrum includes a receive portion of the radar system to receive a reflected signal from the target. A mixer mixes the reflected signal with a shifted signal to obtain a mixed signal. The shifted signal is a shifted version of a transmitted signal that results in the reflected signal and the Doppler spectrum is defined by a frequency shift value of the shifted signal. A processor processes the mixed signal to obtain the velocity measurement.

Abstract: A vehicle, system and method of driving the vehicle. A radar system obtains a measured location of an object in an environment of the vehicle. A processor predicts a location of the object, determines a distance between the predicted location of the object and the measured location of the object, determines a confidence level for the predicted location the object based on the determined distance, selects a tracking state for the object based on the confidence level, and drives the vehicle to avoid the object according to the tracking state of the object. The processor and radar system may be onboard the vehicle.

Abstract: A target detection system and a method of performing radar target detection are described. The system includes a radar system to obtain radar echoes from a target with multiple point reflectors. The system also includes a processor to obtain a cluster of multi-dimensional point spread function from the radar echoes, each multi-dimensional point spread function being associated with a reflection from one of the multiple point reflectors, and also to perform object detection based on three or more dimensions of each of the multi-dimensional point spread functions of the cluster.

Abstract: A vehicle, driving system and method for driving a vehicle is disclosed. The driving system includes a radar system, a processor and an autonomous driving system. The radar system obtains an SAR measurement of a static object in an environment of the vehicle. The processor obtains a first estimate of a location of the vehicle in the environment, obtains from a database a representation of a static object in the environment associated with the first estimate of the location, and compares the SAR measurement of the static object to the representation of the static object from the database to obtain a second estimate of the location of the vehicle. The autonomous driving system drives the vehicle through the environment based on the second estimate of the location of the vehicle.

Abstract: A system and method synchronize two radars by transmitting a linear frequency modulated first signal from a first radar, receiving a first reflection at the first radar based on the first signal, transmitting a linear frequency modulated second signal from a second radar, and receiving a second reflection at the second radar based on the second signal. A fast Fourier transform is performed on the first reflection and on the second reflection to obtain a first frequency-domain signal and a second frequency-domain signal. The first frequency-domain signal and the second frequency-domain signal are converted to the time domain to obtain a first time-domain signal and a second time-domain signal. The first time-domain signal and the second time-domain signal are processed to obtain a time difference in transmission of the first signal and the second signal, and the two radars are adjusted based on the time difference to synchronize subsequent transmissions.

Abstract: A method and system estimate the location of a target using a radar system. A beam pattern is obtained for each of one or more transmit antenna elements and a plurality of receive antenna elements. The method includes transmitting from at least one of the one or more transmit antenna elements, and estimating the location based on comparing a gain indicated by the beam pattern associated with each of the plurality of receive antenna elements and comparing gains of reflections resulting from the transmitting.
