Abstract: A user-centric driving-support system for implementation at a vehicle of transportation. The system in various embodiments includes one or more vehicle sensors, such as a camera, a RADAR, and a LiDAR, and a hardware-based processing unit. The system further includes a non-transitory computer-readable storage device including an activity unit and an output-structuring unit. The activity unit, when executed by the hardware-based processing unit, determines, based on contextual input information, at least one of an alert-assessment output and a scene-awareness output, wherein the contextual input information includes output of the vehicle sensor. The output-structuring unit, when executed by the hardware-based processing unit, determines an action to be performed at the vehicle based on at least one of the alert-assessment output and the scene-awareness output determined by the activity unit. The technology in various implementations includes the storage device, alone, and user-centric driving-support processes performed using the device and other vehicle components.

Abstract: A system and method for resolving a first target from a second target by radar is disclosed. The system includes a transmitter for transmitting a source signal, a receiver for receiving first and second echo signals from reflection of the source signal from at least a first target and a second target, respectively. A processor is used to subtract the first echo signal from the composite signal to obtain a second generation of the second echo signal, subtract the second generation of the second echo signal from the composite signal to obtain a second generation of the first echo signal, and estimate a parameter value for the first target from the second generation of the first echo signal and a parameter value for the second target from the second generation of the second echo signal.

Abstract: A radar system and method of determining a tracking parameter for a target in a radar system is disclosed. A transmitter transmits a source signal at a target and a receiver receives an echo signal from the target corresponding to the source signal. A processor provides a discrete frequency spectrum for the echo signal, shifts the discrete frequency spectrum in frequency space by a selected amount to obtain a shifted spectrum, filters the shifted spectrum using a filter that is shifted in frequency space a same amount as the shifted spectrum, and determines a tracking parameter of the target from a central frequency of the frequency space at which an intensity of the shifted and filtered spectrum is a peak intensity.

Abstract: A method is disclosed for optimizing an angular resolution across a field-of view for an antenna array having a plurality of antenna elements positioned along a curved surface. The method includes selecting a position along the curved surface for a first antenna element in the plurality of antenna elements and calculating subsequent positions for each of the remaining plurality of antenna elements on the antenna array, wherein the subsequent positions are determined relative to the position of the first antenna element and wherein the subsequent positions represent positions at which a maximum angular resolution is achieved for all angles in the field-of-view.

Abstract: Methods and systems are provided for controlling a radar system of a vehicle. In particular a method and apparatus are taught for a predictive tracking algorithm for predicting the power of a target cluster for the next frame and determining a predicted cluster power for the next frame. The updated power of the next cluster frame is a function of the predicted power, the current measured power and the SNR of the environment. The power of cluster is computed taking into account the energy backscattered by each detection inside the cluster.

Abstract: A method of synchronizing a plurality of spatially distributed multi-input multi-output (MIMO) radar systems includes designating one of the plurality of MIMO radar systems that includes a linear frequency modulator as a master MIMO radar system, and designating each of the other plurality of MIMO radar systems as slave MIMO radar systems. Each of the slave MIMO radar systems receives an output of the linear frequency modulator. A synchronization signal is sent from the linear frequency modulator through the modulator splitter to each of the slave MIMO radar systems over respective cables, and a return signal is sent from each of the slave MIMO radar systems to the master MIMO radar system over the respective cables. A time delay is determined between the master MIMO radar system and each of the slave MIMO radar systems based on a frequency difference between the synchronization signal and the respective return signal.

Abstract: A radar system mounted on a platform includes a transmitter turned off during a silent interval, and a receiver to receive one or more signals resulting from transmission by one or more other radars that transmit linear frequency modulated signals during the silent interval. A processor estimates parameters of the one or more other radars. The parameters include bandwidth and slope of the respective linear frequency modulated signal and the parameters are used to modify a transmitted signal or the processing by the radar system.
