Ongoing Research Initiatives
This initiative pursues two branches of sonobuoy-based underwater communication technology to improve situational awareness. The first is a method of layering a sonar pulse with a gentle signature that allows for source validation and deconfliction at the receiver. The second method is a communication scheme that uses modified sonobuoys to transmit acoustic packages to unmanned underwater vehicles.
HoloGRAMS (Holistically Optimized GRAMS) substantially enhances ASW capabilities and significantly reduces operator workload. HoloGRAMS applies advanced signal processing techniques to leverage low SNR and “out of band” signatures, performs additional information processing to improve signal metadata quantification, and integrates efficient data visualization strategies to consolidate vast pools of sensor data into actionable intelligence. HoloGRAMS supports both the Navy’s need for an automated yet transparent ASW analysis tool but also commercialization opportunities in FMS and civilian markets.
The USA Echo Repeater is a testing platform developed to support the development of next generation and experimental sonobuoys. Utilizing expertise in system prototyping, DSP, and acoustic array development, SDi has designed the water-deployable unit to serve the needs of the Navy for a configurable and real-time data acquisition and response system. The Echo Repeater operates as a self-contained and recoverable product, allowing for continuous remote operation until all sonobuoy testing has been concluded and reuse for future test efforts.
RDA’s Acoustic Interference Mitigation (AIM) provides enhanced ASW capability in contested environments. AIM improves Probability of Detection (Pd) in presence of acoustic jammers (friendly or foe) and significantly reduces or mitigates high-energy acoustic interference for both passive and active ASW sensors and missions. The AIM technology has low system impact, is sensor-agnostic, and has wide application to ensure costeffectiveness.
