摘要：

We numerically study and compare the noise suppressions in the chaos lidar (CLIDAR) and the synchronized choas lidar (S-CLIDAR) systems with the optoelectronic feedback (OEF) and the optical feedback (OF) schemes. The S-CLIDAR system with both OEF and OF schemes show better noise immunity than the CLIDAR system in the low SNR region. Compare with the OEF scheme, the S-CLIDAR system with the OF scheme is more sensitive to the phase noise. For the S-CLIDAR system with both schemes, an open-loop configuration under a generalized synchronization condition is desired.
