summary

System converts commodity vehicle Radar into coherent SAR that outputs 3D point clouds by combining self cross-range tracking with a multi-focusing step and elevation estimation across vertical antenna pairs. Implementation runs on a TI cascade radar with 6 transmit, 8 receive antennas and uses a ZED stereo camera for ground truth. MilliPoint achieves wavelength-scale localization of the radar, resolves specular reflections by detecting focusing centers in the spatial frequency spectrum, and produces much denser, higher-resolution point clouds of cars, pedestrians, bikes and bins compared with noncoherent and static-radar baselines.
