Compact Sonar Surveillance Processing Systems

This paper outlines a recently developed COTS system for sonar surveillance applications. It uses an open architecture and commercial operating system, together with programmable DSP cards, to realise a compact unit that has been deployed in a number of operational sonar applications. The system can be configured by the operator for a variety of surveillance and classification processing tasks and for data recording and replay/re-processing, for post event analysis. Functionally, the system provides the baseline processing to handle current generation surveillance arrays deployed by the UK Navy, as well as a number of enhancements to improve the flexibility and operational effectiveness of these types of system.
