摘要： Systems and methods for performing over-the-air verification tests for radar. A test chamber includes multiple sections, the sections separated by metal walls. The inner surfaces of the metal walls include absorbers. Each section includes defined testing devices to verify a defined function of a radar device. The defined testing devices can include a horn antenna and corner reflector. Each section has a defined number of rows. Each row has a defined testing device. Test fixtures hold a defined number of the radar devices in correspondence with the defined number of rows. The defined number of the radar devices placed on the test fixture via a placement device. A positioner to align under the sections and move the test fixtures through the sections of the test chamber and a controller to control operation of the positioner, the radar devices, and the placement device to execute over-the-air verification of the radar devices.

摘要： A computer is programmed to receive first sensor data from a sensor of a vehicle indicating a first relative position of a stationary object, the first relative position detected while the vehicle is in a first vehicle pose; receive second sensor data from the sensor indicating a second relative position of the stationary object, the second relative position detected while the vehicle is in a second vehicle pose having a different orientation than the first vehicle pose; and determine one of a calibration parameter or a vehicle relative pose based on the first relative position, the second relative position, and the other of the calibration parameter or the vehicle relative pose. The calibration parameter defines a sensor pose of the sensor relative to the vehicle. The vehicle relative pose defines a transformation of the vehicle from the first vehicle pose to the second vehicle pose.

摘要： A vehicle measurement and ADAS inspection and/or calibration system incorporating dual support columns arranged in a front-to-back configuration on a rolling base to achieve a low center of gravity. A vertically adjustable instrumentation and target support lateral crossbeam is mounted to a front column and is linked to a counterweight supported on a rear column by a driven cable and pulley assembly. A storage cabinet is additionally located on the wheeled base, partially enclosing a lower portion of the rear column, and extending forward towards the front column. Brake releases are operatively coupled to associated friction brake pads located below the base. The friction brake pads are biased into engagement with a supporting floor surface to prevent unintended movement of the base, and temporarily disengaged by operation of the associated brake releases.

摘要： The present disclosure is directed to simulating patterns of reflected radar energy off of reference objects using motion data associated with these reference objects. This motion data may identify start times, start locations, end times, and end locations of a limited number reference objects in a set of discrete scenes. Each of these discrete scenes may also have a same time duration. Motion of these specific objects between a start time and an end time of each discrete scene may be interpolated. Once the locations of the objects are interpolated for a given scene, simulations may be performed to estimate the appearance of reflected radar signals that would be received by a radar apparatus. These simulations may identify patterns of reflected radar energy after radar signals have been emitted from the radar apparatus and these patterns may then be provided to train a machine learning apparatus.

摘要： A frequency modulated continuous wave (FMCW) radar system is provided that includes a receiver configured to generate a digital intermediate frequency (IF) signal, and an interference monitoring component coupled to the receiver to receive the digital IF signal, in which the interference monitoring component is configured to monitor at least one sub-band in the digital IF signal for interference, in which the at least one sub-band does not include a radar signal.

摘要： Railroad crossing object detection systems and methods include radar sensors detecting object presence, speed and heading in a different manner. A controller compares signal outputs from the different sensors to provide traffic control preemption signals and self-diagnose sensor problems. The sensor devices may include an ultra-wideband (UWB) impulse radar device and at least one reflective device providing failsafe object presence detection and object non-presence detection in redundant fashion with at least a second sensor device such as a side-fired radar device.

摘要： Devices, systems, and methods are provided for radar elevation angle measurement. A radar elevation angle measurement system may transmit one or more signals from a radar towards a reflection structure comprised of individually controlled motors operable to rotate one or more corner reflectors. The radar elevation angle measurement system may receive echo signals at the radar from each of the one or more corner reflectors that sequentially transitioned to an ON position based on each of the one or more corner reflectors being sequentially rotated to be in an ON then an OFF positions. The radar elevation angle measurement system may collect data associated with the echo signals received from the one or more corner reflectors. The device may identify peak signal values based on the collected data. The radar elevation angle measurement system may calculate a radar pitch angle of the radar based on the peak signal values.

摘要： A method of operating a radar system includes: receiving a range-angle image (RAI) and a range-Doppler image (RDI) that are based on raw data from a radar sensor of the radar system; choosing, from a list of potential tasks, a task for the radar system to perform based at least on the RAI and the RDI; and modifying one or more parameters of the radar system in accordance with the chosen task for the radar system.

摘要： The present disclosure generally relates to sensor calibration and more specifically, to sensor calibration using weather data. In some aspects, the present disclosure provides a process for receiving a set of weather data from a weather measurement station disposed within a calibration environment, determining if a predetermined weather condition is indicated by the set of weather data, and collecting, using one or more AV sensors, a set of sensor data within the calibration environment, if the predetermined weather condition is indicated by the set of weather data. Systems and machine-readable media are also provided.
