Submarine high frequency active sonar for own
ship safety and tactics.
MOAS provides high detection performances and ensures that the submarine is always in a safe environment to
maneuver.
­Mine & obstacle detection and localization
Safe shallow waters navigation.
Mine fields avoidance.
­Detection of surface obstacles
Highly important for submarine safety when surfacing.
­Bottom mapping for 3D Navigation
Real-time visualization of seabed (Nav 3D), localization & tracking of contacts.
­Short range submarines detection
Management of short range situation with very quiet submarines.

SUBMARINE WARFARE
MOAS
Mine & Obstacle Avoidance Sonar
Essential for the safety of submarines operating
increasingly in littoral waters, the real-time 3D
navigation capability also provides potential for better
own ship geographical localization (based on correlation
with existing charts or sea-marks).
The MOAS provides also a good short range detection
capability of cooperative or non-cooperative platforms
in the vicinity.
MAIN CHARACTERISTICS
TECHNICAL FEATURES
Bandwidth: 36 to 72 KHz
Range coverage: 1Km approx.
Range accuracy : better than 0.5 m at 1 km*
Bearing accuracy: 1.5° at 54 KHz ahead of submarine
Bearing coverage: +/-45°
Elevation coverage: Sector of 24°, 12° or 6° Steerable
elevation coverage
* Ahead of the submarine, static point target, assuming perfectly known
velocity profile
System features:
• Easy to integrate by shipyards
• Stand alone or fully integrated sonar in S-CUBE sonar
suite
• 3D real time visualization for obstacles and bottom
mapping
• Automatic 3D localisation enabled by wide band,
frequency coded transmission and 3D forward bottom
mapping
• Selectable narrow elevation beams and wide frequency
band provide very good performance against
reverberation, especially in shallow water, and provide
high probability of detection against moored mines
• Detection and tracking, low absorption losses and
good discretion level
• Automatic detection and tracking provides the operator
with the capability to manually send a detected mine
or obstacle location to the tactical system
• D isplay in graphical form uses a Man Machine
Interface (MMI) with a high-resolution colour display
• Easy to interface MOAS with combat management
system (CMS) and navigation systems (electronic
charts)
