3D camera HydroVision SeaStar24

2Dacousticfor marine applications

Brief description
HydroVision SeaStar24 is a passive underwater acoustic imaging platform designed for surveillance of sensitive maritime environments. Using a dense 24-channel hydrophone array and phase-coherent signal processing, the system converts ambient underwater sound into spatial 2D and 3D visualizations without emitting acoustic signals.

Passive underwater monitoring – benefits

• Emission-free monitoring (no acoustic transmissions)
• Discrete surveillance of sensitive areas
• Reduced environmental disturbance
• Situational awareness without acoustic signature

Technical core elements

• 24-channel hydrophone array
• Digital beamforming (real-time)
• Phase-coherent signal processing
• Real-time acoustic source localization
• 2D and 3D acoustic imaging

Real-time 2D and 3D acoustic visualization
The system reconstructs acoustic fields from naturally occurring sounds and presents acoustic activity in an intuitive spatial view, improving interpretability compared with spectral-only analyses.

Typical applications

• Security monitoring of critical maritime infrastructure
• Port and offshore facility surveillance
• Monitoring of offshore wind turbine foundations
• Inspection of subsea cables and pipelines
• Marine research, acoustic source mapping and eco-sensitive monitoring scenarios
