Submarine and Surfaceship Acoustic Range (SAR)

L3 Oceania develops sophisticated solutions to measure and communicate data through water. The
company specialises in applications involving underwater test and evaluation and through-water communications.

The Submarine Acoustic signature measurement Range (SAR) is based on an application recently provided to one of our customers.

SAR is an ultra-low noise acoustic measurement range incorporating co-operative tracking and highly automated data analysis and management software.

SAR can measure the signatures of submarine and surface vessels. It is a fixed installation comprising a submerged hydrophone array and electronics bottle connected via a fixed underwater cable to a control centre housed in a shore range centre.

For submarines SAR employs the Submarine Tracking System (STS) developed for other related L3 Oceania signature measurement systems. STS provides in water range measurement to provide a highly accurate input to the acoustic sound pressure level (ASPL) calculation. STS also provides information on the platform’s current operating state.
