Polarimetric characterization of debris and faults in the highway environment at millimeter-wave frequencies.

Polarimetric characterization of debris and faults in the highway environment at millimeter-wave frequencies.

In this paper, measurements and models for the polarimetric backscatter response of various paint targets on roads and road surface faults are presented. Of particular interest are debris and faults that could lead to fatal accidents and damage of property. A desired safety feature for automotive ra...
