Principle of Underwater Acoustic Communication (UAC)
Underwater Acoustic Communication (UAC) devices, also known as underwater acoustic modems, are designed to enable reliable long-range underwater communication where traditional radio frequency (RF) or optical signals cannot propagate effectively.
The principle of UAC is based on using acoustic waves (sound waves) as the carrier of information. Since water absorbs electromagnetic waves quickly, sound waves are the most efficient medium for 10 km underwater communication and beyond.
How it Works
-
Signal Modulation & Transmission
Data from surface or subsea platforms is converted into digital signals and then modulated into acoustic waves using techniques such as PSK, FSK, or advanced spread spectrum. These modulated sound waves are transmitted through water. -
Propagation in Water
Acoustic waves travel efficiently through seawater, even at long ranges, though they are affected by temperature, salinity, pressure, and multipath reflections from the seabed and surface. -
Reception & Demodulation
The receiving underwater acoustic modem captures the sound waves with hydrophones, then demodulates the acoustic signals back into digital data for further processing.
Applications
UAC technology is widely used in:
- Marine data transmission for environmental monitoring and oceanographic research.
- Buoy communication systems, where floating buoys act as relay nodes.
- AUV communication and USV acoustic links, providing control and data exchange for autonomous platforms.
- Long-range underwater communication networks, connecting subsea sensors and instruments for offshore engineering and ocean monitoring.
By leveraging the physics of sound propagation, UAC devices provide a stable, low-power, and scalable solution for subsea connectivity, making them a cornerstone technology for the future of intelligent ocean exploration.
