Compressive Full Waveform LiDAR with Low-cost Sensor

摘要

Full-waveform LiDAR is a method that digitizes the complete waveform of backscattered pulses to obtain range information of multi-targets. To avoid expensive sensors in conventional full-waveform LiDAR system, a new system based on compressive sensing method is presented in this paper. The non-coherent continuous-wave laser is modulated by electro-optical modulator with pseudo-random sequences. A low-bandwidth detector and a low-bandwidth analogdigital converter are used to acquire the returned signal. OMP algorithm is employed to reconstruct the high resolution range information.
