Zusammenfassung:	Embodiments of this application provide a signal processing method and apparatus, relate to the field of laser detection technologies, and may be applied to self-driving or assisted driving. In embodiments of this application, accuracy of peak-point signal strength and peak-point receiving time of a received pulse signal can be improved. The method includes: A laser radar determines a first probability distribution of M rising-edge sampling points distributed on each waveform in a preset waveform set; determines a fifth probability distribution indicating that each waveform in the preset waveform set is a received pulse signal; determines, based on the first probability distribution and the fifth probability distribution, a sixth probability distribution indicating that the received pulse signal is each waveform in the preset waveform set; determines a first preset waveform from the preset waveform set based on the sixth probability distribution; and determines the peak-point receiving time and the peak-point signal strength of the received pulse signal based on the first preset waveform.
