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.


  • Major Benefits:

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.
