SS2030

The main purpose of the SS2030 sonar is to detect submarines, and it has special capabilities for operation in littoral and shallow waters where strong reverberation may be a limiting factor more tha natural noise. Wide pulse bandwidth together with high beam Directivity Index (DI) and good receiver sensitivity provide good resolution and detection performance against weak targets. Hence, this sonar also has excellent capability for detection of midget submarines and underwater drones in the water column.

The sonar has a hull unit with a hoistable cylindrical multi-element transducer array. Each transducer element is electronically and individually controlled. This advanced electronic steering provides stabilization of acoustic beams for compensation against ship roll and pitch movements. The cylindrical array provides a 3D search coverage of the water volume and beams can be electronically tilted up and down by operator control. By use of the audio channel output the operator can listen to audio signals in any direction of interest. The transducer array configuration in combination with real time beam stabilization and steering enable 3D target tracking.

The built-in Computer Aided Target Acquisition (CATA) software provides both manual and automatic target track initiation. The sonar can be offered with built-in "Torpedo Management" capability for handling detections and tracks that are classified as torpedo. A built-in sound propagation modelling tool is available to the operator, which helps the operator find the best sonar setup and the optimal tilt angle that provides the maximum detection range of the day.

The SS1221 is prepared for information exchange with a Combat Management System (CMS). The integration is flexible and can be via single or dual LAN (copper or fibre). Additionally, the sonar is prepared for remote control via radio link (e.g. the MBR), and all sonar functions can be remotely controlled.
