FMCW Laser Ranging Beyond Coherence Length Based on Digital Phase Noise Compensation
Two-step digital phase noise compensation is used to overcome the limit of coherence length. Chirp-z transform is used to roughly estimate the beat frequency to reduce the iterations so that fast compensation is achieved. © 2024 The Author(s)
