The present disclosure relates to detecting road surface conditions. A road surface detector comprises a transmitter, receiver, and one or more processors. The transmitter is configured to transmit one or more radio frequency (RF) beams at a road surface. The receiver is configured to receive RF reflections of the one or more transmitted RF beams at two or more receive channels. The one or more processors are to determine a road surface condition based on a doppler signature of the received RF reflections. A method comprises transmitting one or more radio frequency (RF) beams at a road surface. RF reflections of the one or more transmitted RF beams are receives at two or more receive channels. The method includes determining a road surface condition based on a doppler signature of the received RF reflections.
