abstract={This report investigates the ability to determine road conditions with radiometric remote
sensors, in order to detect ice or water at a distance. The project consists of the development
of a theoretical model, with associated assumptions and delimitations, numerical
simulations in COMSOL Multiphysics as well as experimental measurements to verify
or dementiate the theoretical model. The concept of detection uses the surface dielectric
constant’s dependance of material, which means that radiation from the atmosphere
will be polarized differently upon reflection. Experiments were made using artificial road
surfaces similar to real road conditions. In order to carry out the experimental measurements,
a radiometer was constructed.
The conclusion is that the concept has the potential to differentiate between the road
surfaces asphalt, water and a thick and smooth layer of ice. Some exact thresholds for
polarization difference require further measurements. For layer structures that have a
rough uppermost layer the theoretical model of the project has great difficulty to predict
the polarization difference, but potentially further development can help model these
cases better.},
