Electromagnetic Modeling of Concealed Targets

This research project will focus on the concealed target detection challenge. In particular, target signatures will be analyzed to determine how the signatures change as a function of radar viewing angle, transmitted radar frequency and bandwidth, and target orientation.  In addition, the impact of embedding the target in or behind a dielectric layer will be examined. Targets of interest could include: personnel behind walls, buried walls, buried landmines, and obstacles hidden in foliage. The model results will be used to determine if targets of interest exhibit an unique radar scattering behavior that could be exploited to separate targets from clutter objects. In addition, the model results will be used to predict the performance capabilities and limitations of foliage and ground penetrating radar technology for Army applications.
