Abstract
A light detection and ranging (LIDAR) system for a vehicle, includes a laser source configured to output a beam, a transmitter, a receiver, one or more optics and a processor. The transmitter is configured to transmit a transmit signal that is generated based on the beam. The receiver is configured to receive a return signal reflected by an object in response to the transmit signal. The one or more optics are 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. The processor is configured to determine a type of the object by processing a signal-to-noise ratio (SNR) value of the first signal and a SNR value of the second signal.
