Abstract
A system for providing three-dimensional (3D) imaging using radio frequencies (RFs) includes a millimeter-wave (mmWave) radar chip on a mobile robot comprising antennas, the mmWave radar chip configured for rotating to emulate a cylindrical array of antennas. The system further includes an RF imaging system that receives, by the rotating antennas, RF signals, estimates locations of the rotating antennas when the RF signals were received, processes the RF signals received by the antennas using the estimated locations of the antennas to provide 3D imaging; and enhances resolution of the 3D imaging using machine learning.
