A light detection and ranging (LiDAR) system including a plurality of light emitters, wherein the plurality of light emitters are configured to emit a plurality of beams, and the plurality of light emitters are configured to form a beam polarization pattern of the plurality of beams to be emitted toward an object external to the LiDAR system, a receiver that is configured to receive light reflected from the object, and an analyzer that comprises a processor and programming instructions that are configured to cause the processor to determine characteristic differences between the beam polarization pattern of the beams emitted toward the object and an intensity pattern of the light reflected from the object, determine a reflection position that is associated with the light reflected from the object, and use the determined characteristic differences to determine whether the reflection position is a position of the object or a position of a ghost.
