The ARPA Vela program developed sensors to detect nuclear explosions in space, the upper atmosphere, and underwater to support the 1963 Limited Nuclear Test Ban Treaty, under which the United States, Great Britain, and the Soviet Union banned atmospheric tests of nuclear weapons. The first VELA sensors, deployed on a pair of satellites launched three days after the treaty was signed, were designed to monitor for optical and electromagnetic signatures of nuclear explosions in the atmosphere.

Later in the 1960s and 1970s, DARPA oversaw the development of the World Wide Standardized Seismograph Network (WWSSN) for detecting underground nuclear tests. The Agency also helped expand detection technologies globally and internationally by running workshops, funding research projects in other countries, and championing community-building initiatives.

Biological warfare agents pose more than a hypothetical threat to U.S. military servicemembers. Troops operate in hostile areas where they could come under attack from adversaries wielding bio-agents like anthrax and toxins. The first step in reacting to any such attack is knowing that it occurred. Quickly and accurately identifying the presence of airborne antigens can be difficult given their complexity, the presence of numerous similar microorganisms in the environment, and the fact that even minute quantities of a threat agent can cause infection.[i]

Raman spectroscopy uses lasers to measure molecular vibrations to quickly and accurately identify unknown substances. Ultraviolet (UV) lasers have the optimal wavelength for Raman spectroscopy at stand-off distances, but the Defense Department’s (DoD) current UV-based tactical detection systems are large and expensive and have limited functionality. A new DARPA program seeks technology that may make UV-based detection equipment more readily available in the field.

Seeking to expand the nation’s capability to detect and identify materials that are not easily visualized by conventional imaging technologies, DARPA today released an announcement inviting proposals to develop portable, next-generation imaging tools that combine the complementary benefits of X-ray and neutron radiography.

DARPA yesterday issued a solicitation for proposals responsive to its Spectral Combs from UV to THz (SCOUT) program, which seeks new capabilities for highly sensitive remote detection of multiple biological or chemical agents in liquid or gaseous forms. A proposers day is set for Oct. 15 via webcast.
