Matched filtering and instantaneous frequency fitting recover FMCW lidar ranges beyond the Nyquist limit from the full waveform despite frequency-domain aliasing, with fitting more robust to phase noise.

FMCW Lidar Beyond Nyquist by Instantaneous Frequency Fitting
Matched filtering and instantaneous frequency fitting recover FMCW lidar ranges beyond the Nyquist limit from the full waveform despite frequency-domain aliasing, with fitting more robust to phase noise.
