RAP-Based Mooring System Enhances Long-Range Deep-Sea Acoustic Detection
At 4050 meters down in the northern South China Sea, ambient noise drops, and detection sharpens. This study's RAP-based subsurface buoy system, built around a co-oscillating sphere-type vector hydrophone rated for 5000 meters, proves that depth itself can become an acoustic advantage. The sea trials confirm what the physics predicted: bearing estimation works where conventional paths fail. It is a practical step toward persistent deep-sea listening.
Enhanced Bearing Estimation for Weak Underwater Targets Amid Interference
Weak-target bearing estimation in the South China Sea no longer demands blind guesswork. This study pairs square-root cubature Kalman filtering with adaptive bearing interval constraints, cutting root mean square error from 121.67° to 14.72° under interference-to-signal ratios near 3 dB. That is a measurable leap in ocean intelligence. The method's precision matters most when broadband signal-to-noise ratios hover near -2 dB. For readers tracking subsurface acoustics, related work on RAP-based mooring systems offers complementary insight into long-range detection challenges.
