Abstract
The embodiments of this application disclose a time of flight measurement method, including: performing delay processing on an echo signal to obtain N delayed signals; generating X clock signals with different phases based on a multi-phase clock unit; performing delay latch on the N delayed signals based on each of the X clock signals; determining a to-be-processed time of flight based on the reference signal and each of the delay latch result; and determining a target time of flight based on the X to-be-processed time of flights, where the target time of flight is a time difference between emitting the reference signal and receiving the echo signal. With the embodiment of this application, the precision of measuring the time of flight of the echo signal can be effectively improved while saving costs and simplifying calculations.
