Millimeter-wave scattering from dry sand-covered surfaces

This paper examines recently acquired polarimetric data of dry sand with smooth air/sand interface at MMW frequencies. The data characterizes volume scattering from different types of sand as a function of the radar incidence angle, frequency, polarization, and particle size. The data shows substantial volumetric response from dry sand at MMW frequencies with significant depolarization (between -12 and -7 dB).
