摘要： A radar sensor for use within a vehicle includes blockage detection functionality. In at least one embodiment, the radar sensor collects information on stationary infrastructure around the vehicle. The infrastructure information may be used to generate a Doppler Monopulse Image (DMI) or other graph for the sensor. A clutter ridge within the DMI or other graph may be analyzed determine a blockage condition of the sensor (i.e., unblocked, partially blocked, or fully blocked).

摘要： A blockage detection system and methods for use in a sensor are described. The blockage detection system and method operate in systems including two or more sensors having overlapping field-of-views (FOVs). The blockage detection system includes a storage in a first sensor having stored therein a tracked object list including detections/tracks for one or more targets made by a second sensor and a processor for adjusting an overlap zone associated with the first sensor based upon an estimated mounting angle of the first sensor. The system further includes a processor configured to identify one or more relevant detections/tracks from the tracked object list using the adjusted overlap zone and a blockage detection processor configured to receive the relevant detections/tracks from said processor and configured to compare the relevant detections/tracks to detections/tracks for one or more targets made by the first sensor.

摘要： A radar sensor for use within a vehicle includes self calibration functionality for performing angle calibrations for the sensor when the sensor is mounted within the vehicle. In at least one embodiment, the radar sensor collects information on stationary infrastructure around the vehicle for use in calibration operations. The infrastructure information may be used to generate a Doppler Monopulse Image (DMI) or other graph for the sensor. A clutter ridge within the DMI or other graph may then be analyzed to determine calibration data for the sensor.

摘要： Described are a method and apparatus for detecting static objects and broadside objects in a vehicular radar system. Detection data within a field of view (FOV) for a host vehicle is acquired. A histogram process determines presence of at least one of a static object and a broadside vehicle. The histogram process includes generating ratios of a relative velocity of an object (Vr) to host velocity (Vh) from acquired detection data and determining a number of detections which occur at an angle α corresponding to an intersection of two lines with a first line represented by Vr/Vh = 0 and a region of a second line within the FOV along which Vr/Vh ≠ 0. The detections are filtered to identify detection points at first and second predetermined values of α, wherein the identified detections indicate presence of a static object and/or a broadside vehicle.
