Diver Detection Sonar
DDS ( Diver Detection Sonar) is a specialized sonar designed to detect and identify small underwater objects classified as small targets, i.e. a diver, a small underwater vehicle, floating explosive charge. DDS converts received target echoes giving on exit information about underwater objects registered together with the detection parameters (range, bearing, type of object). Working continuously DDS tracks objects detected and starts an alert, if the object detected constitutes threat - criteria of threat are defined the user of the object protected.
The operating parameters of DDS depend on hydro-metrological conditions in the water area to be protected and topography of the object protected ( e.g. of harbor) must be taken into account for placing it.
Functions:
- The structure of the sonar and its parameters can be made to match the water area geometry (shape, configuration, type of bottom) sas well as changing propagation conditions in the water area.
- It can operate with other sonar systems of that type to make an integrated system - cable, radio, or acoustic based communication.
- It can operate with active acoustic barriers in bi- and multi-static systems - cable, radio or acoustic based communication among sonar systems and modules of a barrier
- It is resistant to interference from other sonar systems working in the same sea area as well as to interference generated by sources of interference.
- It can track up to ten underwater objects.
- It has a built-in auto-diagnostic system
