Principle of Underwater Acoustic Communication (UAC)
The UAC-08160X-SE4T is a high-performance underwater acoustic communication device designed to overcome the limitations of radio and optical signals in water. Since electromagnetic waves attenuate rapidly in seawater, sound waves become the most effective carrier for long-range underwater communication. With the help of an underwater acoustic modem, digital data can be reliably transmitted even in complex ocean environments.
How It Works
-
Modulation & Transmission
Data from AUV communication systems or subsea platform communication nodes is converted into digital signals and modulated using FSK, PSK, or spread spectrum techniques. The signals are then transmitted into the water column via a transducer. -
Propagation in Water
Acoustic waves can travel long distances underwater. Under favorable conditions, systems such as the UAC-08160X-SE4T can achieve 10 km underwater communication, while also supporting 6000 m deep-sea communication for extreme subsea applications. -
Reception & Demodulation
Hydrophones capture the incoming signals, and the underwater acoustic modem demodulates them back into digital data, enabling stable and accurate marine data transmission.
Typical Applications
- AUV communication – Provides reliable acoustic links for autonomous underwater vehicles to support navigation, control, and data exchange.
- Subsea platform communication – Enables data transfer for seabed bases, observatories, and offshore engineering platforms.
- Buoy communication – Floating buoys act as relay nodes to transmit underwater data to surface stations.
- Ocean monitoring – Long-term environmental and scientific observation, transmitting data such as temperature, salinity, currents, and acoustic imagery.
- Deep-sea research – With 6000 m deep-sea communication, supports exploration, geological surveys, and resource assessments.
Advantages
- Long-range underwater communication up to 10 km.
- High adaptability to varying salinity, temperature, and pressure conditions.
- Multi-platform compatibility, supporting AUV communication, subsea platform communication, and buoy communication.
- Low-power operation suitable for long-term ocean monitoring missions.
