【 摘 要 】

A non-intrusive approach for personal surveillance is explored.A potential strategy for identification of electronic devices using electromagnetic illumination with the aim of identifying unique resonances and signatures is presented.The concept is that signatures can be compared to a known signature for a particular device. If discrepancies are detected, then the device may be flagged as a suspect item.Various antenna structures are analyzed to determine the ideal antenna characteristics needed for electromagnetic illumination.A double ridged horn antenna is designed, characterized and compared to a conical spiral right hand circular polarized antenna and a standard gain antenna. Various passive structures and electronic devices are illuminated with electromagnetic energy and responses analyzed.
