| Summary: | Person-borne weapons and explosives present major security threats at infrastructures such as airports. Advanced imaging technology such as millimeter-wave whole body imaging systems are used to identify anomalous objects hidden underneath people's clothing. There is a high demand to improve the efficiency and accuracy of the reconstructed images the systems produce. A next generation millimeter-wave portal scanner is being developed by the ALERT Homeland Security Center of
Excellence. A fundamental part of the design phase includes utilizing simulation tools to predict the scattering behavior of objects-of-interest, to model hardware configurations at minimal cost, and to develop model-based inversion methods. |
