Hardware‐Efficient FMCW Laser Ranging Beyond the Coherence Length Approaching the Wiener Phase Noise Limit

ABSTRACT Coherent ranging based on frequency‐modulated continuous‐wave (FMCW) lasers is highly promising for autonomous systems. However, the high‐cost laser source hinders the large‐scale deployment of FMCW lidar, which requires both narrow linewidth and large tuning bandwidth....
