Expands our exploration of the effects of the soil environment on landmine detection by investigating the influence of soil texture and water content on surface soil temperatures above antitank mines buried at 15 cm depth and away from it. Temperature distributions in July were calculated in six soil textures (sandy loam, loam, silt, silt loam, sandy clay loam, and clay loam) for the climatic conditions of Kuwait and Sarajevo. We evaluated the temperature distributions in typical dry and wet soil profiles. The simulated temperature differences varied from .22-.63 degree Celsius in Kuwait to .16-.37 in Sarajevo. Temperature differences were larger in the wet than in the dry soils which suggests that soil watering may help improve thermal signatures. The thermal signature of an anti tank mine strongly depends on the complex interaction between soil texture, water content, and geographical location. This modeling study indicates that the use of a thermal sensor in a real mine field for instantaneous mine detection carries a high risk. On the other hand if a given area can be monitored constantly with a thermal sensor for twelve hours or longer the thermal signature will be detected.
