Abstract:
The Transportation Security Administration (TSA) was created in response to the terrorist attacks of September 11, 2001, to ensure the safety of the traveling public. One of their primary responsibilities is the screen of luggage and passengers at airports across the country. Since their creation, TSA has invested heavily in Advanced Imaging Technology (AIT) for the screening of passengers due to the detection limitations of traditional metal detectors.

Millimeter-wave imaging has proven to be the dominant AIT technology as it is safe, fast, and relatively inexpensive. TSA continues to invest in improving AIT image quality and reducing scanner cost. In this thesis, a novel approach to millimeter-wave hardware and system architecture is presented that allows for higher-quality images at a lower than currently available.

Lower system cost is achieved by replacing traditional radar hardware with fully integrated, wide-bandwidth, high-speed communication chips. The new hardware is used in a patented architecture that allows it to be used in place of specialized radar hardware, at substantially lower cost. The hardware is used in a system architecture that combines a novel blade-beam reflector with a multi-static receiver array that enables higher-speed imaging, reduction of artifacts, and higher resolution images than current scanners.
