Abstract: This study presents experimental measurements of dielectric constant of dry and moist soils at C-band microwave frequency by using waveguide cell method. Soil samples were collected from four locations each from four different Indian states. An automated microwave set-up operating at 5.3 GHz frequency is used for this purpose. Measured values of dielectric constant are then used to estimate emissivity and scattering coefficient by using emissivity model and perturbation model respectively. Emission and scattering properties for soils are then studied as function of gravimetric Moisture Content (MC, %), polarization and incidence angle. At constant value of MC, emissivity of soil is found to increase with increase in the incident angle for vertical polarization, and this increase continues up to Brewster’s angle and beyond this, emissivity decreases sharply.
