The Domestic Nuclear Detection Office (DNDO) has issued a Request for Information (RFI) about potential technology to improve aerial stand-off radiation measurement systems for the detection of special nuclear material and other radiological material from an airborne platform. The agency is especially interested in detecting and locating point-like sources in a complex and dynamic background in urban, maritime and coastal environments. The concept of operations is more in line with law enforcement practices. In particular, DNDO is seeking information on two fronts: improved detection systems, hardware and packaging; and sensor fusion that combine radiation measurements with other sensor data and advanced algorithms to enhance nuclear and radiological threat detection, localization and identification. The main carriage platform would be rotary-wing aircraft although fixed- wing and other airborne or mobile ground based platforms are also of interest. The agency’s objective is to replace the current state-of-the-art in aerial radiation monitoring with technology that can process data in real-time and make a detection decision in a single pass over a suspect target while improving sensitivity, location accuracy and isotope identification. Sol. No. DNDO-10-Airborne-Standoff. Respond by April 30. Contact: William Fuller, contract specialist, 202-254-6829, [email protected].
