1. A method of operating a light detection and ranging (LiDAR) device, the method comprising:
obtaining receiving signals corresponding to reference laser pulses generated from a reference signal;
obtaining a main receiving signal having a maximum value among the receiving signals with respect to a time point;
correcting a value of a sub-receiving signal at the time point based on the maximum value of the main receiving signal, wherein the sub-receiving signal comprises a receiving signal corresponding to a scan angle deviated by an angle at which a side lobe is generated from a scan angle of the LiDAR device corresponding to the main receiving signal; and
obtaining a time of flight (ToF) of a laser pulse corresponding to the sub-receiving signal based on a cross-correlation function between the corrected value of the sub-receiving signal and the reference signal.
