Embodiments of the present disclosure are drawn to apparatuses, systems, and methods for range peak pairing and high accuracy target tracking using frequency-modulated continuous-wave (FMCW) light detection and ranging (LiDAR). A laser source may illuminate a target with a first laser chirp pair during a first time period and a second laser chirp pair during a second time period. Based on the configuration of the chirps between the pairs and within the pairs, properties of the target may be determined. For example, range estimates may be made based on each chirp pair, and those estimates may be averaged to cancel out a Doppler shift error. In another example, the Doppler shift may be determined, which may increase the accuracy of a range measurement and/or be used to identify which peaks are associated with a given target.
