Paper Abstract

Under a current Army Research Office Multi-University Research Initiative, Georgia Tech has engaged in the development of detailed environmental models for studying the impact of various soil and environmental processes on landmine signatures. Under this effort, several landmine and false target physics based models have been developed; these models cover the three general cases for landmines: buried, flush-buried, and surface landmines. Each model was developed in concert with a corresponding soil model; specifically, a detailed thermal model of a landmine was incorporated within a correspondingly detailed thermal model of the soil. These models incorporate high spatial resolution (≤ 5.5 cm), three-dimensional heat transfer mechanisms, and environmental influences (i.e., meteorological information, subsurface processes) into the signature computations. This paper will present a detailed description of the models, the environmental processes currently incorporated and example signature results for both LWIR broadband and hyperspectral sensors. The representation of various soil processes in the models will also be included in the discussion.
