Paper Abstract

The purpose of this simulation is to compare the backscattered coefficients (or backscattered signals) among four different explosives (TNT, COMP B, TETRATOL, and PICRATOL) and two materials (STEEL and ALUMINUM). All six will be independently buried under four different sources: dry soil, and then moist soil independently covered with snow, with ice and finally with water. The four explosives were selected to represent non-metallic mines and STEEL and ALUMINUM were selected to represent metallic mines. The backscattered coefficient of a mine is calculated using the concept of pulse reflections and transmissions at junctions and pulse attenuations in the materials. A short pulse with a constant, initial voltage progresses through four junctions of different materials such as Antenna and Air, Air and Snow, Snow and Soil, and Soil and Mine with resulting pulses reflected, transmitted at these junctions and pulse attenuated in these materials. The product of the transmission ((tau) ) and reflection ((rho) ) coefficients ((tau) 1(tau) 2(tau) 3(rho) 4(tau) 3'(tau) 2'(tau) 1'), the attenuation factors (e-2(alpha airlair)e-2(alpha soillsoil)), and the initial voltage is the backscattered signal from the mine. The backscattered coefficient of the mine is the ratio of the final voltage to the initial voltage in decibel.
