Marine Electronics 3D Sand Ripple Profiling Logging Sonar
|SeaVoX Device Catalogue
|Mar Elec 3D SRPLS
|A dual axis mechanically scanning sonar unit with a built in hard disk drive and associated controlling computer, powered by an external battery pack but is self-contained. The sonar has an oil-filled hemi-spherical plastic "boot" providing protection for its acoustic transducer which operates with a narrow conical beam pattern. Typically the sonar is mounted vertically, looking down at the sea-bed, and captures a sequence of profiles of the sea-bed over a pre-programmed sector and range. The sonar gathers a single swath of data in the horizontal plane and then rotates the transducer through a pre-programmed angle around the vertical axis and repeats the process until a circular area underneath the sonar has been scanned in a sequence of radial spokes. The raw data represents the signal amplitude of the envelope of the returned echoes. A suite of sensors to measure conductivity, temperature, depth, pitch and roll are also mounted on the instrument.
