This application discloses a LiDAR anti-interference method and apparatus, a storage medium, and a LiDAR. The method is applied to a LiDAR, and the LiDAR includes a laser emission array and a laser receiving array. The method includes determining at least two laser emission units to be turned on in a measurement period, controlling the at least two laser emission units to emit laser beams based on a preset rule, and controlling respectively corresponding laser receiving units of the at least two laser emission units to receive echo beams, to detect a target object. The at least two laser emission units to be turned on are in different laser emission groups, and the at least two laser emission units to be turned on satisfy a physical condition of no optical crosstalk.

LiDAR anti-interference method and apparatus, storage medium, and LiDAR

A radar data transceiver, a ranging method, and a LiDAR are provided. The transceiver includes: a synchronization module, configured to generate a synchronization signal and send the synchronization signal to an emission module and a receiving module separately; the emission module, connected with the synchronization module and configured to delay the synchronization signal according to a preset delay policy, generate a first emission signal, and emit the first emission signal; and the receiving module, connected with the synchronization module and configured to receive a reflected signal, generate a first histogram according to the reflected signal and the synchronization signal, and superimpose histograms obtained by n measurements to generate an echo signal.

Radar data transceiver, ranging method, and lidar

A method for Doppler scan conversion includes storing coded envelope values together with spectrum data in a memory out of a logic device with a large capacity, which increases the number of envelopes stored, reduces the use of the restricted embedded memory resources, and can also achieve the envelope switching more flexibly. If the number of envelopes is not greater than the difference between the bit width of the memory and that of the spectrum data, the increase in the number of envelopes will not increase significantly the logic resources or affect the efficiency of the system.
