    "body_text": "Cameras and LiDAR can degrade in darkness or bad weather, while spinning radar remains available but difficult to interpret. StreamRPS pairs labels built from LiDAR scene completion with a radar-specific transformer that preserves range and angular structure. On the SAX and BOREAS datasets, the authors report at least a 1.4-point gain over the strongest evaluated baseline and throughput above 400 frames per second in a four-sector configuration. They also release manual annotations for 100 SAX scans. This is not an autonomous-driving safety certification, but it pushes radar from sparse detections toward real-time scene structure.",
