Paper Abstract

This paper presents a non-destructive procedure to determine the surface hardness of the soil using an elevated radar system equipped with a focused-beam antenna. The complete system consists ofthe focused beam antenna, a network analyzer, a computer, and control software that process the data. The surface dielectric constant calculated from the radar data based on reflection measurement was compared with the surface hardness measured directly from a homemade hardness meter. A sand pit was used as test bed that was frozen by liquid nitrogen. It was found that there is a simple and direct relationship between the surface hardness and the measured dielectric constant in our case.
