Checked Baggage

Checked baggage screening system The Checked Baggage Program has three specific focus areas:

  • Advanced X-ray Systems Development – Development and testing of full up system engineering design models (EDMs) (TRL 6-7 level of maturity).
  • Advanced Algorithms and System Integration – Development/maturation of threat detection and false alarm reduction algorithms, integration into operational /prototype systems and demonstration of real time operation.
  • Supporting Component Technology Development – Development/maturation of system components and subsystems (such as X-ray Sources and Detectors) necessary to evolve laboratory and experimental prototypes into full up X-ray system designs able to meet the Advanced X-ray Systems requirements.

 Future Program Capabilities: 

  • An expanded library of explosives and explosives signatures that can be effectively detected
  • Improved automated explosives detection and false alarm performance
  • Improved imaging tools for operator alarm resolution
  • Improved system reliability, screening speed (throughput) and reduced cost of ownership compared with currently deployed explosives detection systems (EDS)
