Azimuth Super-Resolution for FMCW Radar in Autonomous Driving
Computer Vision and Pattern Recognition, 2023We tackle the task of Azimuth (angular dimension) super-resolution for Frequency Modulated Continuous Wave (FMCW) multiple-input multiple-output (MIMO) radar. FMCW MIMO radar is widely used in autonomous driving alongside Lidar and RGB cameras.

Orthogonal waveforms for FMCW MIMO radar
2011 IEEE RadarCon (RADAR), 2011Multiple input/multiple output (MIMO) radar system performance benefits from the capability to simultaneously transmit and receive multiple orthogonal waveforms. For pulse radars fitting orthogonal waveforms have been developed. These waveforms are however not necessarily suitable for frequency-modulated continuous-wave (FMCW) radar.
