Abstract
A LiDAR range and speed measurement method and a LiDAR, are disclosed. Through the technical solution provided by the embodiment of the present application, it is possible to determine whether Doppler aliasing occurs based on a first local oscillator signal generated by a first laser and a second local oscillator signal generated by a second laser, the first local oscillator signal including multiple segments of first continuous wave signals, the second local oscillator signal including multiple segments of second continuous wave signals, the second continuous wave signal including a first swept frequency signal and a first constant frequency signal. In the event of Doppler aliasing, a first algorithm is used to calculate the distance and/or speed of the target object relative to the LiDAR, thereby improving the accuracy of the LiDAR ranging and speed measurement.
