RadarGaussianDet3D: Gaussian Representation-Based Real-Time 3D Object Detection With 4D Automotive Radars
RA-L 2026
4D automotive radars have gained increasing attention for autonomous driving due to their low cost, robustness, and inherent velocity measurement capability. However, existing 4D radar-based 3D detectors rely heavily on pillar encoders for BEV feature extraction, where each point contributes to only
