Paper Abstract

A test and evaluation pilot study was conducted in January 1996 at Sea-Tac International Airport in Seattle, Washington to determine the initial effectiveness of the Millimeter- wave Holographic Weapons Surveillance System. This is a new personnel surveillance systems for the detection of concealed metal, plastic, and ceramic weapons and other threatening materials. Two different frequency bands were used in the study: Ku band and Ka band. Over 7000 Millimeter-wave (MM-wave) holographic images were obtained on 21 different models. The 7000 images were used to produce simulated real-time surveillance system videos. The videos were constructed by obtaining 36 images of the models at 10 degree increments for 360 degree coverage. A library of two hundred videos were produced for this pilot study: 100 at Ku band and 100 at Ka band. The videos contained either a threat or no threat. The threats were concealed at different locations on the models. Various innocuous items and different clothing combinations were also used n the construction of these videos. Twenty-nine certified Sea-Tac screeners were used in the initial test and evaluation of this new surveillance technology. Each screener viewed 160 MM-wave videos: 80 Ku band and 80 Ka band. The ratio of non- threat to threat videos per band was three to one. Test and evaluation software was developed to collect data from the screeners on-line for the type and location of threat detected. The primary measures of screener performance used to evaluate this new technology included, the probability of detection, the probability of a false alarm, measures of screener sensitivity and bias, and threat detection time.
