The U.S. Navy is seeking innovative solutions through the Small Business Innovation Research (SBIR) program to enhance submarine mast detection and discrimination capabilities using coherent radar waveforms. The primary objective is to exploit the radar backscattering return from the wake produced by a moving submarine mast, thereby improving detection performance beyond what is achievable with the mast return alone. This initiative addresses a critical challenge in maritime surveillance, as effective detection of submarine masts is vital for national defense and maritime security. Interested parties should note that the solicitation is set to open on January 8, 2025, with proposals due by February 5, 2025, and further details can be found at the official SBIR website.
