title = "Frequency Nonlinearity Compensation of FM Lidar System Using Hilbert Transform and Interpolation Resampling",
abstract = "FMCW lidar measures distance using time-varying frequency modulation, and its linearity affects resolution. We employed the Hilbert transform, frequency-domain interpolation resampling, and an auxiliary interferometer (with a 0.315 m arm length difference) to compensate for frequency nonlinearity, thereby achieving a 25-fold improvement in spatial resolution and verifying its feasibility under low-bandwidth conditions.",
