Paper Abstract

This paper describes scene simulation in passive millimeter wave imaging. The appearance of flat metal and plastic objects is simulated, as viewed from a grazing incidence angle, using a passive millimeter wave imager. The assumptions and essential physics behind the simulation are reviewed. The simulations are made in the atmospheric window at 90 GHz. Experimental data taken at 35 GHz is presented for comparison. It is demonstrated that metal objects have generally low radiation temperatures in relation to their environments. Plastics on the other hand can have higher or lower radiation temperatures than their backgrounds, dependent on the polarization, the type of earth, its condition and the amount of water present. In the cases demonstrated in this paper the simulations agree well the experimental data.
