Measurement of soil backscattering with a 60-GHz scatterometer

Experiments designed to measure the backscattering coefficient of soil surfaces were performed indoors using a 60-GHz scatterometer. The roughness of the soil surface was measured with a laser profile meter to determine the roughness dependence of the scattering coefficient. The incidence angle dependence of the measured backscattering coefficient shows distinctive features according to the roughness of the soil surface. These results are compared with estimates from a small-perturbation theory.<
