摘要：

We have designed an anti-interference LiDAR based on frequency-hopping (FH) modulated for autonomous vehicles. It uses the cross-correlation method to analyze and process the signals. The effectiveness of the anti-interference capability of the LiDAR is verified by ranging relative error (RE). The result shows that the RE of range measuring is minor than +/- 0.9%. It demonstrated that the proposed LiDAR in the letter provides a reproducible and reliable way to realize ranging detection. In addition, the experiment results testify that the system has an excellent anti-interference capability with other interference of LiDARs.
