Abstract
This paper studies 24-GHz automotive radar technology for detecting
low-friction spots caused by water, ice, or snow on asphalt. The
backscattering properties of asphalt in different conditions are studied
in both laboratory and field experiments. In addition, the effect of
water on the backscattering properties of asphalt is studied with a
surface scattering model. The results suggest that low-friction spots
could be detected with a radar by comparing backscattered signals at
different polarizations. The requirements for the radar are considered,
and a 24-GHz radar for road-condition recognition is found to be
feasible.
