Principle of Underwater Acoustic Communication (UAC)
Underwater acoustic communication devices (UACs) are critical systems that enable data transmission in aquatic environments where electromagnetic and optical signals cannot propagate effectively. Due to the low attenuation and stable propagation of sound waves in water, UACs are the most effective solution for long-range underwater communication. They are widely used in ocean monitoring, marine data transmission, buoy communication, AUV/USV links, and seabed base communication.
How It Works
-
Modulation & Transmission
Digital data is first processed by a subsea acoustic modem (underwater acoustic modem), which applies modulation techniques such as PSK, FSK, or multi-carrier methods. The signals are converted into sound waves by a transducer and transmitted through water. -
Propagation in Water
Acoustic waves can travel several kilometers underwater. In favorable conditions, UAC systems can achieve 10 km underwater communication. However, the signals are influenced by temperature, salinity, pressure, and multipath effects caused by reflections from the surface and seabed. -
Reception & Demodulation
At the receiving end, hydrophones capture the acoustic signals, which are then demodulated by the underwater acoustic modem back into digital data, ensuring reliable data delivery.
Shallow-Water vs. Deep-Sea Applications
- Shallow Water: Suitable for buoy communication, coastal environmental monitoring, and real-time ocean data transmission between AUVs and USVs.
- Deep Sea: Advanced models support 4000 m deep-sea communication, making them essential for seabed base communication, long-term ocean observatories, and subsea research platforms.
Advantages & Value
- Long-range underwater communication up to 10 km for reliable remote monitoring.
- Low-power operation enables extended deployment in long-term missions.
- High adaptability to variable marine environments.
- Widely applied in marine data transmission, buoy communication, seabed base communication, and ocean monitoring.
