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 radar system and method of configuring a radar system that includes two or more antennas to transmit a respective transmit waveform. Two or more waveform generation devices include respective modulation elements. Each of the two or more waveform generation devices has a one-to-one correspondence with one of the two or more antennas, and each of the two or more waveform generation devices generates the respective transmit waveform for a first period of time and generates an arbitrary response for a second period of time.

Abstract: A method and system perform perimeter security and control of a vehicle. The system includes a radar system arranged in the vehicle, a maximum range of the radar system being less than 100 meters, and a communication unit to communicate with the radar system. The system also includes a control system of the vehicle to control the platform based on the radar system. The control system dynamically controls each door of the vehicle according to a location of the communication unit relative to the platform.
