Abstract
A system and method for correcting a Light Detection And Ranging (LiDAR) return signal is disclosed. The LiDAR return signal is digitized by a converter. An exemplary signal correction system includes a signal processor configured to identify saturated samples from the LiDAR return signal, determine a correction parameter based on non-saturated samples in the LiDAR return signal and corresponding samples in a reference signal, and correct the saturated samples in the LiDAR return signal using the correction parameter.
