The NEW
965A High Speed High Resolution Imaging Sonar.
The Imagenex Model 965A is an advanced, high-speed, high-resolution,
multibeam imaging sonar system that has been designed to provide simple,
reliable, and accurate representation of underwater images.
The system consists of an underwater sonar head connected by Ethernet to
a Windows™ based computer.

- Advanced Sonar Interpretation with Image Stabilization
Every ROV pilot struggles with vanishing
targets when operating all previous scanning sonars. During the
approach with an ROV or other moving platform, the change in vehicle
heading will move targets out of the viewing sector of the
sonar on successive sweeps. In order to re-locate the object the
operator must increase the sector or stop the ROV and sit on the
bottom to attempt to relocate.
Smaller unwanted changes in rotation of
the sonar platform will either compress or expand the scan of the
target causing distortion and loss of bearing to the object.
By combining a gyroscope and a magnetic
compass with the sonar head, the new 881L-GS sonar is capable of
correcting for orientation changes at a rate in excess of 500
degrees per second. This allows compensation for sudden turns,
bumping, and jarring. Scan lines are displayed without blurring,
compression or smearing effects in all modes of operation.
A North-up mode references the sonar image
to true north when using an appropriate variation input: regardless
of ROV heading changes, the sonar is able to keep the target
continuously at the center of the scanning sector. Positional
changes of aspect relative to the target are easily compensated by
clicking the 'Set Gyro Reference' button on the screen.
For use as a drop sonar suspended from its
umbilical, this system provides a simple solution offering reliable
and stable screen image orientation during most types of operation.
Simultaneous Display and Recording of your
ROV Video on the 881A/L-GS computer.
The benefits of these new features are
vastly reduced sonar image distortion, resulting in significantly
improved object recognition.
Greatly increased operational efficiency in searches due to the
ability to operate with much narrower search sectors with higher
update rates, and without the need to re-acquire a target.
Easy recognition of bottom features within the search area due to
minimal distortion.
