Our two-channel underwater acoustic analysis system is designed to determine the direction of underwater acoustic sources by processing audio signals received from hydrophones.

The system features an architecture that allows external hydrophones to be connected directly. Underwater sounds detected by the hydrophones are transmitted to the system through two separate channels and analyzed using the developed signal processing algorithms.

The direction of arrival of a sound source can be estimated by evaluating the time, phase, and amplitude differences between the signals received through the two channels. This enables the monitoring of underwater acoustic events and the determination of sound source directions.

Key system features:

• Two-channel hydrophone connectivity
• Real-time or recorded-signal analysis of underwater acoustic signals
• Evaluation of signal differences between the two channels
• Estimation of the direction of an acoustic source
• Flexible system architecture compatible with different hydrophones
• Software and hardware infrastructure adaptable to underwater acoustic monitoring and research applications

Our solution is based not on hydrophone manufacturing, but on *acoustic analysis and direction-finding technology* that extracts meaningful information from hydrophone data. This approach enables the use of existing hydrophones while delivering its primary added value through signal processing, analytical algorithms, and direction-finding capabilities.

In conclusion, our system is a two-channel technological solution designed to process underwater acoustic data and determine the direction of sound sources, with integration capabilities for different hydrophones.
