Patent attributes
A method in a lidar system comprises emitting a pulse of light, detecting at least a portion of the emitted pulse of light scattered by a target located a distance from the lidar system, and determining the distance from the lidar system to the target based at least in part on a round-trip time of flight for the emitted pulse of light to travel from the lidar system to the target and back to the lidar system. The method further comprises emitting a series of pulses of light having particular pulse-frequency characteristics, detecting at least a portion of the series of emitted pulses of light scattered by the target, and comparing the pulse-frequency characteristics of the series of emitted pulses of light with corresponding pulse-frequency characteristics of the detected series of scattered pulses of light to determine a velocity of the target with respect to the lidar system.
