Abstract: This application discloses a compensation method and apparatus for continuous wave ranging and a LiDAR. The compensation method includes: calculating a reflectivity of an object detected by a receiving unit, querying, based on a preset mapping relation, for a target distance response non-uniformity (DRNU) calibration compensation matrix associated with the reflectivity, and compensating, using the target DRNU calibration compensation matrix, for a distance of the object detected by the receiving unit.
