Paper Abstract

The effects of soil and mine parameters on microwave imaging are investigated based on Finite-Difference Time-Domain (FD- TD) simulation and laboratory studies. Range of soil permittivity considered is from 2.6 to 7.6 corresponding to dry soil and a volumetric soil moisture of 16%. Both plastic and metallic mines are imaged. The diameter of the mines considered ranges from 9 cm to 32 cm and their height ranges from 4 cm to 20 cm. It is found that when a mine diameter is larger than a wavelength, its image is discernible and becomes clearer when its diameter exceeds two wavelength. It is also found that a plastic mine with a dielectric constant of 3.9 embedded in a dry soil medium with a dielectric constant of 2.6 can generate an image with the correct geometric shape.
