POLARIMETRIC BACKSCATER CHARACTERIZATION OF ROAD SURFACE FAULTS AT MILLIMETER-WAVE FREQUENCIES

This paper focuses on the backscatter behavior of typical road surface faults such as potholes and surface cracks. Examining backscatter behavior is important as road cracks are apt to cause false alarms in collision avoidance systems. Two models are developed to predict the backscatter response of cracks that are perpendicular to antenna boresight. Additionally, the backscatter behavior of potholes with different depths over a wide range of incidence angles is discussed.
