Scanning color imaging sonar Imagenex Fast scanning color imaging sonar

The 881a is a programmable multi frequency digital imaging sonar that you can operate using default frequency settings or customize the configuration for your own situation. It can operate as an fast scanning sonar as well as a profiling sonar to get an accurate seabed profile with its structure on it. High performance, lower cost, low power and simple set up and installation, make this sonar perfect for the largest ROV’s to the smallest inspection ROV’s, plus AUV or UUV applications. USING THE IMAGING SONAR ON AN ROV The imaging sonar is a useful substitute for a positioning system on an ROV. Without an imaging sonar, an ROV relies on travelling underwater to bring new targets into view. With an imaging sonar, instead of traveling it is more useful to spend some time with the vehicle sitting on the bottom while the sonar scans the surrounding area. Scanning a large area takes only a short time, and the vehicle pilot can quickly assess the nature of the surrounding area. The ability to ”see” a long distance underwater allows the pilot to use natural or man-made features and targets as position references.

The combination of an imaging sonar and an ROV leads to fast and effective training in sonar interpretation. If the ROV pilot is searching for a particular object, recognition can take place directly from the sonar image. In other cases a number of potential targets may be seen. A pilot can sharpen his sonar interpretation skills by viewing these targets with the vehicle’s boat video camera and correctly identify them.
