DARPA’s Strategic Technology Office is seeking research and development proposals for BEAMERS, a scalable electromagnetic-support receiver prototype.
- Government buyer: U.S. Department of Defense, Defense Advanced Research Projects Agency (DARPA), Strategic Technology Office (STO).
- Scope: Develop and experimentally validate an integrated, wideband, receive-only staring electronic-support receiver spanning approximately 1–110 GHz. It is intended to provide broad spectral and spatial coverage without scanning across the field of regard.
- Technical approach: Incorporate beamspace processing, frequency channelization, Tier-0 detection, selection of signals of interest, scheduled selective coherent I/Q capture, and a digital test backend.
- Phased demonstrations:
  - Phase 1: Demonstrate complete receive chains for 1×8 or functionally equivalent one-dimensional aperture band tiles.
  - Phase 2: Scale to 8×8 or functionally equivalent two-dimensional aperture band tiles and integrate the prototype, addressing cross-band detection, event association, resource scheduling, and scaling risks.
- Services also include program reporting and deliverables, including technical and business status reports, a data management plan, milestone deliverables, applicable invention reports, and final reporting.
- OEMs, vendors, commercial part numbers, and purchase quantities are not identified. The requested effort is prototype development and demonstration, not a specified commercial-product purchase.
- Proposals are classified; no specific classification level is stated.

### Description

The Defense Advanced Research Projects Agency (DARPA) is soliciting classified innovative proposals to develop and demonstrate prototype staring electromagnetic support systems providing continuous spectral and spatial coverage over a large frequency span without scanning over the field of regard.
