The Department of Defense (DoD) is seeking proposals for a Small Business Innovation Research (SBIR) program focused on the topic of "Solar Blind UV Detector for Space Object Detection". The research aims to develop novel systems to expedite the detection of unknown objects in space. The objective is to develop a high sensitivity wide bandgap based solar blind detector with a UV/V rejection ratio of >105. The technology will be used to equip defense aircrafts and satellites with self-protection sensor systems, specifically warning sensors operating in the ultraviolet (UV) part of the spectrum. The detection range of these sensors is limited, but their false-alarm rate is low. Phase I involves research and development of concepts, while Phase II focuses on building prototype systems and evaluating their performance. Phase III involves applying the knowledge gained to build an advanced sensor suitable for mission application. The project duration and funding specifics are not provided in the document. Foreign nationals are restricted from participating in all phases, and Phase II work is expected to be classified.
