Abstract

Recent investigations into the use of new electro-optical sensing modalities for the detection of landmines and other objects in complex backgrounds have led to the need to understand the optical properties of background materials (e.g., soils) in more detail. In particular, the use of spectral and polarimetric signatures in the optical and infrared domains has been the subject of much study; an understanding of soil, foliage, and other background optical properties and their variations is critical to evaluating the utility of these signatures. Our research examined soil emissive and polarimetric signature characteristics in the context of a real world environment; specifically, we examined the spectral properties of landmines and soils within a complex radiative environment. A modified Hapke radiative transfer model was employed to compute these properties. This paper will present a brief overview of those modifications and results of the optical property computations for several scenarios.
