Description
Automated Threat Detection (ATD)
Body scanners detect weapons and explosives concealed on the persons entering security controlled areas. The best performance is achieved when an operator manually inspects the raw scanned image. However, privacy and manpower concerns have prompted the development of computer software for this task. Often called “Automated Threat Detection (ATD),” this software examines the computerized data from the scanner, detects hidden objects, and displays them as yellow boxes on a ”stick‐figure” body outline .
Automated Threat Detection (ATD)
ATD has many advantages: improved privacy, faster screening, lower manpower costs, and overall simplicity. Most airport body scanners throughout the world now use ATD— but it has come at a terrible price. The US Government recently reported its testing results: ATD‐equipped airport body scanners— using millimeter wave technology— missed 64 of 67 threats.
- Metal and nonmetal threats
- Stick‐figure display (ATD)
- 7‐second scan
- Compact 5’x5′ footprint
- Unaffected by damp clothing
Defender uses a different technology, background‐level x‐rays, with far superior threat detection. Teamed with Tek84’s recent breakthorughs in automated software, Defender provides ATD simplicity, with excellent detection ability.
Defender scans in three separate ways: Backscatter to detect threats on the front and back; Forward‐
Scan for objects concealed on the sides and in loose clothing; and Ground‐Level to inspect the ankles and
feet. Other body scanners rely on a single mode to detect concealed objects, resulting in blind areas on
the body. Triple‐mode detection provides complete coverage from head‐to‐toe.
