Zusammenfassung:	The present invention disclosure describes a new method for a light detection and ranging (LiDAR) estimation that is alternative to the mainstream time of flight (ToF) LIDARs in the particular use of autonomous driving vehicles. The present invention describes a method for range estimation of a received AMCW LiDAR signal comprising the steps of: calculating a spectrogram of an input signal x comprising a frequency bin ƒ RF, n ; calculating a ToF estimation, T ToF , from the spectrogram; calculating a phase Φ 1; calculating an AMCW estimation; calculating a final estimation based on the ToF estimation and the AMCW estimation; calculating a final range dest·
