UAAS - Underwater Acoustic Analysis System

Contract awarded by the Bundesamt für Wehrtechnik und Beschaffung (BWB) for use at the German Navy Hydroacoustic Analysis Centre (HAM)

Builds on the proven design of the Canadian Towed Array Sonar System (CANTASS) Post Analysis System (PAS)

Underwater Acoustic Analysis System

Array was awarded a contract by the Bundesamt für Wehrtechnik und Beschaffung (BWB) for the provision of an Underwater Acoustic Analysis System (UAAS) for use at the German Navy Hydroacoustic Analysis Centre (HAM). The UAAS is the German implementation of Array's ScalableGSP architecture. Array delivered the UAAS in March of 2006 and the project is currently under support and maintenance phase.

The UAAS is an integrated system that uses proven software and the latest Commercial Off-The-Shelf (COTS) hardware technologies to provide the most cost-effective and low risk sonar post analysis system. The UAAS is Array's third generation shore-based sonar post analysis system and it builds on the proven design of the Canadian Towed Array Sonar System Post Analysis System (CANTASS PAS) delivered to the Canadian Navy and the Sonar Acoustic Post Processing System (SAPPS) delivered to the Royal Swedish Navy (RSwN).

The UAAS has evolved from a post analysis system dedicated to a single towed array sonar to a generic shore based processing system with complete analysis tools necessary for all types of sonar systems.

Using Linux and open source standard libraries, the open system is hardware independent and is very adaptable and flexible. The modular software design allows for algorithm customization, it is reconfigurable to accommodate additional future sonars, and its processor capacity can be increased without triggering a need to re-write software.

The UAAS has one central Signal Processor (SP) and four Operator Workstations (OWs). The SP is the control unit of the system and it acts as the Digital Signal Processor (DSP) server with the necessary peripherals. The SP has the capability to process very large amounts of recorded data very quickly and dump it to the RAID unattended. The multiple OWs access the stored data simultaneously via Gigabit (Gb) Ethernet. The OWs provide the operator interface to the UAAS including system control and acoustic data display functions on user selected raw data.
