Abstract: Systems, methods, tangible non-transitory computer-readable media, and devices associated with radar validation and calibration are provided. For example, target positions for targets can be determined based on imaging devices. The targets can be located at respective predetermined positions relative to the imaging devices. Radar detections of the targets can be generated based on radar devices. The radar devices can be located at a predetermined position relative to the imaging devices. Filtered radar detections can be generated based on performance of filtering operations on the radar detections. A detection error can be determined for the radar devices based on calibration operations performed using the filtered radar detections and the target positions determined based on the one or more imaging devices. Furthermore, the radar devices can be calibrated based on the detection error.
