Abstract
An example system for remote sensing of a road surface includes an antenna configured to transmit and receive radiofrequency (RF) signals, where the antenna is configured to attach to a front end of a vehicle; at least one radiofrequency identification (RFID) tag, where the at least one RFID tag is configured to attach to the front end of a vehicle; and an RFID reader, wherein the RFID reader is configured to: cause the antenna to transmit a radiofrequency signal toward a road surface, where the at least one RFID tag receives a backscattered RF signal from the road surface; receive, from the antenna, an RFID signal from the first RFID tag, the RFID signal comprising phase and magnitude information; and analyze the phase and magnitude information to determine a condition of the road surface.
