Multibeam diver detection sonar -
DDS 9000 ™ series
Introduction
Requirements for shipborne diver detection sonars specify horizontal
coverage of either 200° or 360°. The DDS 9000 covers a horizontal arc of 200°, while
the DDS 9001 provides full 360° coverage. Both diver detection sonars employ bandwidths
much wider than earlier versions, giving improved range performance. Targets are
detected at longer ranges due to improved signal-to-noise ratios using pulse compression
(chirp). Sensors in every sonar head compensate for changes in pitch, roll, or bearing,
ensuring the most accurate target position possible. Proper functioning is assured
through a built-in self test function. Meets US Homeland Security's cost requirement
and is designed for both military and civilian markets.
Flexibility

Applications include fixed systems for port security and mobile systems where
manoeuvrability is important. The systems multimission capability makes it easily
interchangeable from one type of deployment to another. With sonar heads weighing
less than 90 kg (200 pounds) it is light enough to be deployed by a small crew in
less than one hour. Both systems can be lowered by a winch cable, tripod mounted
in a fixed position, or used in mobile and temporary deployments. All DDS heads
are equipped with pitch and roll sensors as well as an azimuth (bearing) sensor,
enabling their use in portside or shipborne applications. DDS systems can be easily
integrated into larger C2 /C4ISR systems to increase situational awareness.
Reliability
Automatic track classification and filtering keep the false alarm rate to a minimum.
Updated electronics based on the renowned SM 2000™ system have been extensively
tested to ensure reliable operation. All metals and devices used in construction
of the DDS 9000 series are carefully selected for their corrosion-resistant properties.
With over thirty SM 2000 systems deployed in the diver detection field, we have
demonstrated the effectiveness and reliability of our systems worldwide. Systems
are in use with the US Navy, US Coast Guard Service, and other military and government
agencies.
