摘要：
Time-frequency analysis is critical for frequency-modulated continuous wave (FMCW) ranging method, especially for spectral-scanning FMCW LiDAR. We use the Short-time Fourier transform (STFT) and wavelet transform (WT) to analyze the time-frequency relationship of the beat signal. Compared with STFT method, the resolution performance of WT is improved.
