A Hybrid Frequency Estimation Framework for Long-Range FMCW LiDAR Under Low-SNR Conditions
Frequency-modulated continuous-wave (FMCW) light detection and ranging (LiDAR) has become increasingly significant for long-distance ranging fields. However, the beat signal is vulnerable to noise interference during detection, resulting in a low signal-to-noise ratio (SNR) and inaccurate ranging results. Although trad...
