Signal processing for IUSS global undersea surveillance system to be upgraded by Lockheed Martin

SAN DIEGO, 15 Oct. 2010. U.S. Navy anti-submarine warfare (ASW) experts are choosing the Lockheed Martin Corp. Information Systems & Global Solutions-Defense segment to upgrade the Navy’s common Integrated Undersea Sensor System (IUSS) Integrated Common Processor (ICP) system to enhance underwater surveillance and situational awareness. The IUSS helps Navy operators locate and track surface ships and submarines in wide areas of the world.

Lockheed Martin won a $24 million contract from the Space and Naval Warfare Systems Command (SPAWAR) in San Diego to provide sonar signal processing technology updates and new concepts to IUSS signal processing, as well as to provide automatic submarine detection and tracking to reduce operator workload, simplify operator training, keep system development costs down, company officials say.

“The capabilities we are providing will help detect, track, and localize undersea threats faster and more accurately,” says Jim Quinn, vice president -of Lockheed Martin’s Information Systems & Global Solutions-Defense.

The IUSS is a large-area ocean basin surveillance system to track surface ships and submarines over large swaths of the world's oceans. It consists of fixed fields of hydrophones and sonar sensors such as the Sound Surveillance System (SOSUS) and Fixed Distributed System (FDS); the Advanced Deployable System (ADS) relocatable sonar sensor field; the Surveillance Towed-Array Sensor System (SURTASS) aboard long-endurance surveillance ships; and the Surveillance Direction System (SDS) that provides command, control, communications, and data fusion to combine the capabilities of SOSUS, FDS, and SURTASS.
