Abstract

By studying 2D coupled heat and water flow within the soil layer with a buried object, a theoretical model for IR imaging buried object sites is presented. The model uses the soil surface energy and water balance equations to determine soil surface temperature. The inputs required for the computer simulations are weather data, solid thermal and hydraulic properties, and object data. Numerical experiments are performed to examine the effect of soil type, object species, and weather conditions on the variations in skin temperature, which show that the object species, object size, and burial depth can evidently affect image feature of the soil surface. The present model reasonably described the soil thermal and hydrological environments and thus can be applied successfully to IR imaging buried object sites.
