RFI: Best Practices in Distributed General-Purpose Radio Frequency (RF) Signal Processing

The Defense Advanced Research Projects Agency (DARPA) Multi X Office (MXO) issued special notice DARPA-SN-26-90 to gather information on best practices and innovative approaches for distributed general-purpose radio frequency (RF) signal processing. This initiative explores methods to standardize the control, scheduling, and processing of advanced RF systems to enhance performance, efficiency, and interoperability in complex operational environments. DARPA intends to reduce the costs associated with laboratory-scale prototype systems and decrease the time required to port these prototypes to tactical platforms.

The Department of Defense seeks insights into leveraging existing standards, optimizing aperture use, and advancing distributed and heterogeneous computing for RF applications. Research and development for this effort falls under NAICS code 541715 for Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) and PSC code AC12 for National Defense R&D Services; Department of Defense - Military; Applied Research. Responses to this Request for Information (RFI) will be used to inform future program development and interoperability for existing DARPA capabilities.

Submissions are due by July 10, 2026, and should be directed to the SN Coordinator. One attachment, DARPA-SN-26-90.pdf, was published with the notice on June 10, 2026. This federal opportunity is categorized under Departmental Offices and represents an effort to support the Department of War in environments where adaptable RF systems are critical to mission completion.
