Hyperspectral sensing's ability to detect ground disturbances aids in the detection of buried land mines and IEDs. Beyond simply detecting ground disturbance, hyperspectral techniques may also provide information about the source of the disturbance that allows for the discrimination of soil disturbances resulting from landmine or IED burial activity from other disturbance sources such as vehicle movement. The mineralogic makeup of natural soils in the near surface is highly stratified, thus any surface disturbance is detectable as a difference in the surface mineralogy in contrast to surrounding areas. Having knowledge of the mineralogic depth profile of the soil, the depth of the disturbance can also be inferred. Field spectral measurements performed using ASD's FieldSpec® 4 spectroradiometer are the ideal means to characterize mineralogy in soil profiles and so provide the means to collect a soil profile spectral signature database that is key to interpreting hyperspectral surface imagery in terms of occurrence of soil disturbances and the depth of disturbance.
