Claim 16:
17. A light detection and ranging (LiDAR) scanning system, comprising:
a light source, wherein the light source is configured to transmit a pulse group signal, wherein the pulse group signal comprises a plurality of pulses having a characteristic;
a light detector configured to receive a returned pulse group signal, wherein the returned pulse group signal corresponds to the transmitted pulse group signal scattered from a surface; and
a microprocessor electrically coupled to the light source and the light detector, wherein the microprocessor is configured to:
correlate the returned pulse group signal with the transmitted pulse group signal based on the characteristic;
determine a time difference between (1) a time associated with the transmitted pulse group signal and (2) a time associated with the returned pulse group signal;
calculate a distance from the light source to the surface based on the time difference; and
determine a reflectivity of the surface based on a correlation of the characteristic of the pulse group signal with the characteristic of the returned pulse group signal wherein the characteristic includes an amplitude of a correlation peak.
