Abstract
A method of operating a light detection and ranging (LIDAR) system is provided that includes generating a set of optical beams, wherein at least one property is varied across the optical beams, transmitting the optical beams toward a target, and receiving a return signal from each of the optical beams reflected from the target. The method further includes generating detection signals based on each of the return signals, determining, for each of the detection signals, a characteristic of the target to produce a set of data points for the target, and determining an updated characteristic of the target based on the set of data points for the target.
