The U.S. Department of Homeland Security's Standoff Technology Integration and Demonstration Program is designed
to accelerate the development and integration of technologies, concepts of operations, and training to defeat explosives
attacks at large public events and mass transit facilities. The program will address threats posed by suicide bombers,
vehicle-borne improvised explosive devices, and leave-behind bombs. The program is focused on developing and testing
explosives countermeasure architectures using commercial off-the-shelf and near-commercial standoff and remotely
operated detection technologies in prototypic operational environments. An important part of the program is the
integration of multiple technologies and systems to protect against a wider range of threats, improve countermeasure
performance, increase the distance from the venue at which screening is conducted, and reduce staffing requirements.
The program will routinely conduct tests in public venues involving successively more advanced technology, higher
levels of system integration, and more complex scenarios. This paper describes the initial field test of an integrated
countermeasure system that included infrared, millimeter-wave, and video analytics technologies for detecting person-borne
improvised explosive devices at a public arena. The test results are being used to develop a concept for the next
generation of integrated countermeasures, to refine technical and operational requirements for architectures and
technologies, and engage industry and academia in solution development.
