Analysis of a thermal imaging method for landmine detection, using infrared heating of the sand surface

摘要

The detection of a buried surrogate land mine is investigated by use of a pulsed thermographic method driven by a high powered infrared heater. In this experimental and analytical investigation, the surface of the sand is initially heated by infrared lamps and is then cooled by natural convection, and during this second phase a dry layer of sand develops on the surface. The temperature distribution of the dry sand surface is influenced by the presence of the buried mine.
