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.

Abstract: An autonomous vehicle control system includes one or more processors. The one or more processors are configured to cause a transmitter to transmit a transmit signal from a laser source. The one or more processors are configured to cause a receiver to receive a return signal reflected by an object. The one or more processors are configured to cause one or more optics to generate a first polarized signal of the return signal with a first polarization, and generate a second polarized signal of the return signal with a second polarization. The one or more processors are configured to calculate a value of reflectivity based on a signal-to-noise ratio (SNR) value of the first polarized signal and an SNR value of the second polarized signal. The one or more processors are configured to operate a vehicle based on the value of reflectivity.
