DSIT Solutions Underwater Port Security and Sonar Systems

For the past two decades DSIT Solutions has been developing and applying state-of-the-art technology to create advanced sonar systems and C&C applications for defense, commercial, energy and homeland security markets. Our systems are designed to bring customers the latest technology in underwater systems as well as in training and simulation. The company is a subsidiary of Acorn Energy (NASDAQ: ACFN).

Diver detection sonar

DSIT is a world leader in the area of underwater site, energy and harbour security and swimmer detection systems. The company’s AquaShield™ is a diver detection sonar (DDS) system that protects ports, naval bases, energy terminals and offshore platforms against underwater intrusion from divers of any type and from divers on swimmer delivery vehicles under the water.

DSIT’s anti-diver sonar system is a high-performance system with the best available ranges of detection and classification. It is also designed for maximum flexibility with three configuration models available, depending on the geography of the site to be protected: 120°, 240° or 360°.

Portable diver detection sonar

The PointShield™ is a compact, lightweight portable diver detection sonar (PDDS). It offers the same sophisticated software as its bigger brother, the AquaShield DDS, but for shorter ranges, including a fully automatic mode of operation with automatic detection, tracking, threat classification and alert, all of which negate the need for a trained sonar operator. The PointShield was designed for mobility and comes in a convenient, portable carrying case with wheels that makes it simple to move from place to place according to need.

The PointShield’s size and weight make it easy to lift for deployment off boats or piers. The system is sturdy and capable of continuous operation under the water as well, so that it can also be permanently installed.

Portable acoustic range

With the MAR portable acoustic range, DSIT has significantly reduced the expense associated with vessel noise measurement. The MAR accurately measures the radiated noise of submarines and ships. Underwater noise ranging enables navies and shipyards to monitor and control this noise, as well as silencing their vessels. Use of the MAR saves the installation and the maintenance costs involved in operating a fixed acoustic range.

The MAR’s unique design enables rapid deployment from even a small ship at any sea depth, without the need to anchor the range. The MAR portable acoustic range is available with either of two hydrophone measurement array versions, oil-filled or line hydrophone array. Both array types are equipped with a pinger at the end of the array that assists the measured submarine to safely navigate.

Generic and tailored sonar simulators

Effective and efficient training of sonar operators is essential to every modern navy today. Even the most sophisticated sonar system is only as good as the quality of its operators. Based on its technological expertise in sonar and underwater acoustics, DSIT has accumulated hands-on experience in active and passive sonar simulation. Today the company provides both generic and specific sonar simulators for rapid and comprehensive training of all types and levels of sonar operators.

The company’s generic sonar simulator (GSS) is cost-effective and can be tailored to meet the specific needs of individual customers. The software is adaptable to simulate any type of sonar system, including: active/passive hull-mounted sonar (HMS), variable depth sonar (VDS), active towed array sonar (ATAS), dipping sonar, passive towed array, submarine passive medium frequency sonar, flank array sonar, passive ranging sonar, intercept sonar, mine detection sonar, sonobuoys and more.

The DSIT on-board sonar trainer (OST) provides sonar operator training on-board a ship displayed on the ship’s own consoles. The DSIT anti-submarine warfare (ASW) fixed, static sonar trainer for surface ship and air platform ASW teams in technical and tactical ASW operations against submarines under realistic acoustic and sonar conditions. The company’s low frequency sonar (LOFAR) operator trainer (LOT) supports high-level acoustic submarine signature measurement training.

To deliver the most up-to-date equipment, DSIT’s ASW sonar comes with software upgrade programmes.

The company’s flagship trainer is its full mission submarine tactical trainer (STT). This submarine trainer is a full mission trainer that accurately simulates all combat systems present on-board the submarine, including all sonar systems, radar, electronic warfare, weapons, C&C and periscope.

Underwater acoustic signal analysis system

DSIT specialises in the science of sonar and underwater acoustics. Our in-depth understanding has enabled us to develop highly advanced acoustic intelligence (ACINT) measurement and analysis applications for underwater asset protection. The company’s underwater acoustic signature analysis system (UASA) is a shore-based system for low frequency sonar (LOFAR) data collecting, processing, analysis, classification and database management.

The LOFAR data, which consists of acoustic signals radiated by various sources, is received and collected by naval sonar systems (submarine sonars, towed arrays, surface and air platforms, fixed bottom moored sonar systems, sonobuoys, etc.) using a data recording system installed onboard the vessels. These recording systems are installed in submarines, surface vessels and air planes. Once data is collected and the vessel is back in the base, the recorded data is sent for analysis at the central lab to create the navy’s acoustic signature database.

Coastal underwater surveillance system

Designed to serve as a long-range underwater warning system against the threat of submarines and smaller submersibles, the SeaShield is installed along critical coastlines and maritime borders, and is also used as a harbor surveillance system. Its combined active and passive sonar arrays provide a real-time situational picture of the underwater protected area.

The SeaShield is comprised of an active transmit array, large passive receive arrays and an electronic unit installed on the sea bed. The system’s two long receive array strings are composed of multiple hydrophones that pick up the signals returning from underwater objects. The SeaShield supports automatic classification that distinguishes between submarines and other underwater objects. The system sounds an automatic alert siren the moment that a submarine or mini-sub is detected and classified. The underwater threat is continuously tracked by the system and its exact position data is displayed on the screen.

Naval monitoring of the underwater surroundings along their coastlines translates to better security for the navy’s own ships and vessels. In case of alert, the navy is also capable of sending its special anti-submarine warfare (ASW) responders to the exact location of the unidentified submarine.

Using such devices, the company also provides security for oil rigs and platforms.

Hull-mounted sonar

Based on its many years of experience in the field of sonar and underwater acoustics, DSIT is offering a cost effective and adaptable hull-mounted sonar (HMS). DSIT’s HMS can be used for coastal and offshore patrol, autonomous underwater vehicle (AUV) tracking, search and recovery, ASW, surveillance, early torpedo warning and other operations required by navies. The HMS also includes a built in training simulator as well as a built in test (BIT) device.

DSIT supplies HMS upgrades to ensure that the industry is using the very latest technology in the field.
