Computing systems, methods, and non-transitory storage media are provided for obtaining a signal emitted from a Lidar, applying a frequency modulation to the signal to generate an up-scanning direction and a down-scanning direction of the signal, wherein the up-scanning direction and the down-scanning direction are symmetric, suppressing a carrier frequency of the signal in response to the applying of the frequency modulation, applying a frequency modulation to the carrier frequency by shifting a local oscillator to change a symmetry between the up-scanning direction and the down-scanning direction, or adding a phase modulation, directing the signal to a target, and simultaneously determining a velocity and a direction of motion of the target with respect to the Lidar based on frequencies of a reflected signal from the target in the up-scanning direction and in the down-scanning direction.
