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.

Abstract: A radar ranging method, device, electronic device, and computer-readable storage medium are provided. The radar ranging method includes: obtaining a plurality of measurement data sets by sampling at least one echo signal based on a plurality of thresholds in a measurement period, wherein the echo signal is sampled based on one threshold to obtain one measurement data set, and each measurement data set includes at least one measurement data; determining M backup data and N auxiliary data in the plurality of measurement data sets, and obtaining a total composite degree of each backup data; determining target data from the M backup data, based on the total composite degree; and determining a measurement distance based on the target data. The radar ranging method enhances the dynamic range of a LiDAR system, improves the measurement accuracy of the LiDAR and reduces the short-distance detection blind zone of the LiDAR.
