2020 45th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
A dual polarization super-heterodyne radiometer operating between 85 and 100 GHz has been developed and used for surface characterization. The instrument can detect changes from dry to icy road in many environmental conditions (night, fog, rain) by m
