Sonac DTS offers both active and passive modes of operation with two separate wet-end sub-systems, variable depth sonar (VDS) and towed array sonar (TAS), that can be used simultaneously. Basic tool for detection is a medium frequency active anti-submarine warfare (ASW) sonar with superior performance in both shallow and open water conditions, and for different operations. The lightweight design of the system is optimised for detection ranges up to 20km.
This dual-tow sonar system includes real-time signal processing and underwater situational picture. The graphical user interface (GUI) is optimised for combined passive/active operation. The existing Launch and Recovery System (LARS) design for safe handling of the tow bodies can be modified based on the vessel installation requirements or restrictions.
SONAC DTS has been selected onboard Finnish Navy Pohjanmaa-class.
