Abstract

This paper reports on the possibility of modelling thermal effects for detecting mines using infrared imaging systems. Results from experiments made in an indoor test landscape, using a sandbox and a solar panel with measuring instruments, are compared to simulated data from a heat transfer model. The radiation from the panel was varied in order to resemble the solar variation from sunrise to sunset. The different temperatures of the sand surface, the sand at different depths and on the surfaces of the four generic mines were sampled at one-minute intervals throughout the experiments. Infrared cameras working in the 2-5 p.m and 8-12 jam bands were used in order to record images of the sand surface. The camera s
