Abstract: A system and method generate a signal for transmission by a radar system. A bit modulator outputs a bit of a binary code. A digital frequency controller outputs a range of frequencies. An order of the range of frequencies is based on the bit. A phase-locked loop generates a signal for transmission by the radar system. The signal includes a chirp comprising the range of frequencies in the order output by the digital frequency controller.

Abstract: A vehicle radar system and calibration method that provide for system calibration so that target object parameters can be calculated with improved accuracy. Generally speaking, the calibration method uses a number of hypothesized calibration matrices, which represent educated guesses for possible system or array calibrations, to obtain a number of beamforming images. A blurring metric is then derived for each beamforming image, where the blurring metric is generally representative of the quality or resolution of the beamforming image. The method then selects hypothesized calibration matrices based on their blurring metrics, where the selected matrices are associated with the blurring metrics having the best beamforming image resolution (e.g., the least amount of image blurriness). The selected hypothesized calibration matrices are then used to generate new calibration matrices, which in turn can be used to calibrate the vehicle radar system so that more accurate target object parameters can be obtained.

Abstract: A method and radar system and vehicle that tracks an object is disclosed. A source signal is transmitted into a volume that includes the object. A reflected signal is received from the volume in response to the source signal. The reflected signal includes a reflection of the source signal from the object. A range is determined for the object from the reflected signal. A ground signal is estimated at the determined range and an amount of the ground signal in the reflected signal is estimated. The object is selected for tracking based on the estimate of the amount of the ground signal in the reflection from the object.

Abstract: A non-line of sight obstacle detection and localization system and method of detecting and localizing a non-line of sight object include receiving reflections at a detection system of a moveable platform, the reflections including direct and multipath reflections, identifying the reflections associated with static targets to retain the reflections associated with moving targets, and distinguishing between line of sight objects and non-line of sight objects among the moving targets. The method also includes localizing the non-line of sight objects relative to the platform and indicating approaching non-line of sight objects among the non-line of sight objects, the approaching non-line of sight objects moving toward the platform on a path that intersects the platform.

Abstract: A system and method to perform a three-dimensional alignment of a radar and a camera with an area of overlapping fields of view position a corner reflector within the area. The method includes obtaining sensor data for the corner reflector with the radar and the camera, and iteratively repositioning the corner reflector within the area and repeating the obtaining the sensor data. A rotation matrix and a translation vector are determined that align the radar and the camera such that a three-dimensional detection by the radar projects to a location on a two-dimensional image obtained by the camera according to the rotation matrix and the translation vector.

Abstract: An automotive radar system includes a radar camera that captures a sequence of frames of radar images of a field of view of the radar. A boundary detector receives the radar data from the radar camera and detects object boundary data in the radar data. An image processor receives the radar data and the object boundary data and performs image analysis including image deblurring and generating response control signals based at least in part on the radar data and the object boundary data. Response equipment implements one or more response actions based on the response control signals. Object boundary detection includes performing pixel-level Doppler analysis to associate pixel velocities to pixels of the radar data and identifying discontinuities in the pixel velocities. Response equipment may include, for example, one or more of a navigation display, collision avoidance warning, automatic cruise control, automatic braking, and automatic steering.
