Auto-Focus Detection Capability for SONAR Systems
SBIR Opportunity Analysis
The Department of the Navy is seeking an SBIR solution to develop an auto-focus signal processing capability for SONAR systems that improves detection of quiet contacts by hydrophone arrays. The work centers on combining multiple focus ranges and other detection surfaces into a single display that preserves the strongest signal representation while reducing operator workload and avoiding the limits of current ORing and automation approaches. Phase I calls for a concept and feasibility demonstration using an unclassified simulated dataset, while Phase II calls for a prototype research code tested against classified datasets and delivered with a software description document, working code, and test results. The opportunity anticipates later classified work and requires a U.S.-owned and operated contractor with no foreign influence, along with the ability to obtain and maintain secret facility and personnel clearances; evaluation will emphasize earlier detections, longer contact holding, and improved search workflow. The topic is open with applications due June 3, 2026, under solicitation DON26BZ01-NV020.
