The Department of Defense (DOD) is seeking proposals for the topic "Detection and Geolocation of Signals of Interest Given Distributed End-User Devices" as part of their SBIR 24.2 Annual solicitation. The Air Force Research Lab (AFRL) is developing a protocol to leverage the sensing capacity of general-purpose end-user devices, such as smartphones, distributed on the battlefield. The objective of this topic is to develop client-side algorithms to detect signals of interest and anomalous signals, and server-side algorithms to accurately geolocate the source of identified signals. The technology aims to capitalize on the underutilized potential of smartphones on the battlefield and will tie into AFRL's effort to develop a distributed sensor tasking protocol. The project will have a Direct-to-Phase-II (D2P2) approach, with Phase II focusing on the development, integration, and demonstration of proposed client and server software. Successful Phase II technologies may have the potential for Phase III development and commercialization. The project is open for proposals until June 12, 2024.
