Dual Frequency Side Scan
GeoAcoustics Standard Dual Frequency Side Scan Sonar – a low cost sonar for general purpose
surveys.
The GeoAcoustics Dual Frequency
Side scan system has become an industry standard, being the world’s best
selling professional side scan system, with more than 700 systems sold. It offers unparalleled reliability,
flexibility, ease of use and maintenance and is also extremely cost
effective.
The system allows operation using
a single low drag coaxial cable of up to 4000m for operation at up to
1000m depth. The standard aluminium towfish is lightweight enough to be
deployed by one person, or can be fully weighted to allow deeper
operation. The complete towfish and deck unit can be used with most
acquisition and processing systems. There are optional
extras including a full towfish instrumentation package (heading, pitch,
roll, depth, responder options, altimeter), and a stainless towfish. |
GeoAcoustics Digital Side Scan
GeoAcoustics Digital Side Scan
Sonar – an advanced digital system highly suited to ROV & AUV mounting.
The
GeoAcoustics Digital Side Scan (DSSS) is the highest dynamic range single beam
dual frequency side scan commercially available. This highly advanced
system allows precisely repeatable seabed feature mapping in a robust and
reliable package. The system utilises high resolution direct
digital sampling of the received signals, and full digital processing. This new
technology offers unprecedented resolution and dynamic range (24 bit),
simultaneous dual frequency operation (114/410 kHz), digital filters, pulse
width auto adjust to optimise for any sample rate setting and a new high speed
digital link enabling very long lengths of low drag co-axial tow cable to be
used. The system configuration, low power and small size make this system
ideally suited for installation onto a Remotely Operated Vehicle (ROV),
Autonomous Underwater Vehicle (AUV) as well as combined profiler/magnetometer
tow fish.
