Diver Detection


Diver Detection Sonar (DDS)

AquaShield™ is a high-performance Diver Detection Sonar (DDS) system. It is designed to provide permanent underwater security for high value coastal and offshore assets such as Naval Bases, Ports, Oil & Gas Terminals, Offshore Platforms, Underwater Pipelines and Cables, Nuclear Power Facilities and canals.

The AquaShield™ DDS – Diver Detection Sonar supports long range of detection for all types of underwater threats including Divers using Rebreathing Apparatus, Scuba Divers and Unmanned Underwater Vehicles (UUVs). The AquaShield™ architecture is modular to allow maximum flexibility in its deployment and installation. The system offers three sector coverage configurations: 120⁰, 240⁰ and 360⁰. All configurations cover the entire relevant water column.

The system supports fully automatic operation – from detection, through tracking to classification and alert – and thus eliminating the need for a well-trained sonar operator. Its advanced signal processing algorithms ensure the desired combination of very high Probability of Detection (PD) with very low False Alarm Rate (FAR).

The AquaShield is built to last! It is designed to stay under the water for long periods of time with very little maintenance required. It is extremely robust and reliable and can even withstand the detonation of a standard underwater charge (200 gr TNT) at a range of 5 meters.

The AquaShield™ is in operational use at many sites around the world; serving leading navies, coast guards, energy companies, port authorities and VIPs. The AquaShield has an excellent track record in providing reliable underwater security in warm and cold water alike.
