1. A light detection and ranging (lidar) system comprising:
a laser source configured to output a beam;
a transmitter configured to transmit a transmit signal that is generated based on the beam;
a receiver configured to receive a return signal reflected by an object;
one or more optics configured to generate a first signal and a second signal based on the return signal, wherein the first signal and the second signal have different polarizations; and
a processor configured to
calculate a reflectivity value of the object based on a ratio of a signal-to-noise ratio (SNR) value of the first signal and a SNR value of the second signal, and
determine a type of the object based on the reflectivity value of the object.
