Abstract

In this paper the results of our high spatial resolution digital thermal modeling effort are compared against field data. This modeling effort created models for three cases: buried, flush-buried, and surface landmines in combination with a detailed soil model. Under a NVESD airborne countermine data collection program hyperspectral signature data were collected in the LWIR spectral region. These data formed the basis for verification of the signature results generated by our digital hyperspectral landmine model. In particular, hyperspectral thermal signature data were extracted from these airborne countermine measurement data and compared against the results of the digital modeling calculations. Spectral data were extracted from areas on and off identified mine areas and compared against similar areas from our digital model over the same spectral range. The results indicate that good correspondence with the field data was achieved. A discussion of this verification process including the field data extraction procedure, signature modeling computations, and the data comparison results will be presented in this paper.
