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

    摘要: An automotive radar apparatus includes a bit stream modulation circuit configured to generate a bit stream signal at an output thereof and a driver circuit having an input coupled to the output of said bit stream modulation circuit and configured to generate a corresponding driver bit stream signal having a reduced output swing at the driver circuit output. Also included is a filter circuit having an input coupled to the output of said driver circuit and configured to generate a filtered bit stream signal at the filter circuit output. Additionally included is a VCO having an input coupled to the output of said filter circuit and configured to generate an RF output signal at the VCO output. A corresponding method is also provided.

    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: A radar imaging system and technique is described in which the imaging system generates an image and transforms the image into world coordinates taking into account host position and heading. Once in world coordinates, successive radar images can be summed (integrated, averaged) to produce an integrated image having a resolution which is improved compared with an originally generated image.
