Abstract
This report describes the preliminary simulation results of ultra wideband polarized scattering from various types of concealed weapons carried by a human. Results are shown for both isolated weapons as well as weapons in close proximity to a human, simulating a human carrying the weapon. By selecting the frequency range to cover the region of resonance, i.e., when the weapon size is a wavelength, resonant scattering mechanism provides unique spectral features that can be used for detecting these weapons. Our preliminary simulations show that it is indeed possible to use the wideband polarized backscatter to identify concealed weapons carried by humans. The report consists of five parts which address the following topics: 1) literature survey, 2) capabilities of full-wave electromagnetic models: feasibility and preliminary case studies, 3) parametric studies in terms of distance, weapon size, mutual position and polarization, 4) complete system models and their performance in frequency and time domain analyses, and 5) recommendations for system parameters.
