In some embodiments, a method for operating a light detection and ranging (LiDAR) system in an automobile provides a more accurate range estimate by combining multiple processed waveforms which are weighted according to their signal to noise ratios. At least one waveform is transmitted within a first time period, and reflected of an object. The reflected waveform is received and processed to improve the signal to noise ratio (SNR). The processing produces a higher number of output waveforms, such as through processing convolution. The SNR for each of the output waveforms is determined. An estimated range to the object from each output waveform is determined. The estimated ranges are then weighted according to their SNRs, and combined to provide an final determined range to the object.
