Abstract
Techniques for detecting and modifying radar data anomalies using multistage clustering are described herein. In some examples, radar data including a set of radar points may be captured by a vehicle operating within an environment. The vehicle may determine a radar point subset by clustering the radar data based on the range and doppler values of the radar points. The vehicle may analyze the azimuth values associated with the radar point subset, including evaluating the azimuth values of the radar point subset relative to one or more azimuth error ranges determined based on the radar antenna configuration and/or multipath detections. When detecting anomalous and/or invalid radar points having azimuth values within an azimuth error range, the vehicle may modify the subset of radar points to mitigate the anomalous or invalid radar points.
