Extraction of ultra low frequency (ULF) modulation features for underwater moving bodies

Puntos clave

• The extraction of ultra low frequency modulation features improves detection capabilities for underwater moving bodies, enhancing overall signal clarity.
• Analysis highlighted specific modulation patterns that were successfully identified in varying underwater environments, supporting robust modeling approaches.
• Assessment using advanced signal processing techniques revealed significant differences in modulation signatures across different types of moving bodies in water.
• These findings may enable improved tracking and identification of underwater objects, though further research is needed for broader applications.
