Abstract Non‐line‐of‐sight (NLOS) tracking has the ability to detect and locate moving objects which are hidden from direct line of sight. It a number potential applications in autonomous driving, security search‐and‐rescue scenarios. The current approaches for NLOS mostly rely on time‐of‐flight (ToF) LiDAR, mmWave radar or RGB camera. However, they may either have limited resolution need accumulation position velocity. Here real‐time comb‐calibrated frequency‐modulated‐continuous‐wave (FMCW) LiDAR system is proposed demonstrated high‐resolution tracking. A 3D positioning (and velocity) accuracy 2 mm s −1 ) capability realize multi‐object experiment. Importantly, FMCW‐LiDAR approach can obtain velocity multiple snapshot , thus resolving problems measurement origin uncertainty, false alarm, detection overlap multi‐target shows significant practical sensing.
