Under water diver alert is a completely passive underwater monitoring system that provides detection, localization, classification and tracking of underwater intruders. As a passive system, it will cause no harm to the aquatic life or the environment, and requires no environmental approvals. The system is entirely environmentally friendly.
Under water alert system generates a high fidelity/low distortion reproduction of actual noise events, and employs narrow-band signal processing techniques to differentiate between actual intruders and typical, everyday events. Unlike traditional electronic undersea sensor systems that rely on a distributed network of point sensors, every inch of the system’s fiber optic sensor cable is acoustically sensitive ensuring that there are no gaps in coverage. A single cable can be up to 25km long and include hundreds of discrete sensor channels. This provides a much wider area of coverage with no gaps, at a much lower cost than traditional electronic systems
