Research questionHow can stereo 4D radar recover full object motion for robust 3D detection despite clutter and sparse measurements?Raw 4D Radar measurements contain clutter, multipath ghost reflections, and noise, while filtering can remove useful observations. Its Doppler measurements capture only radial velocity, leaving the object's full motion state incomplete for 3D detection.
