High-precision UUV direction-finding method based on communication awareness

With the rapid advancement of underwater communication technologies, application scenarios for underwater direction finding and positioning have become increasingly diverse. However, the complex underwater propagation environment, noise interference, and dynamic target characteristics pose significant challenges to high-precision navigation systems, making accurate underwater positioning a critical issue.To address these challenges, a real-time communication-based high-precision underwater direction finding method is proposed. By integrating real-time communication with high-precision direction finding data fusion, a real-time, high-precision underwater direction finding system is developed. The system significantly improves the stability and reliability of direction finding in dynamic underwater environments.Comparative experiments conducted under various scenarios show that the proposed method outperforms existing approaches, achieving a direction finding error of <0.9° This improvement enables more accurate positioning and tracking in complex underwater environments and provides a robust solution for advanced underwater navigation systems.
