The Department of Defense, specifically the U.S. Air Force, is seeking proposals for the SBIR topic titled "RAPTURE – Radio frequency Passive Technology for Ubiquitous Research and Engineering." The objective is to conduct systems engineering, analysis, modeling, simulation, testing, and evaluation of passive Radio Frequency (RF) geolocation technologies that can be applied across various platforms, including both high-end systems and small satellite applications. This initiative is crucial for enhancing situational awareness in contested environments, supporting operational imperatives related to Tactical Air Dominance and Global Strike. Interested parties must submit their proposals by May 21, 2025, with the opportunity to transition to Phase II for further development and testing of prototypes.
