Multispectral Backscatter

R2Sonic manufactures the only MBES capable of surveying at multiple frequencies (up to 5) in one pass and with one system: multifrequency mode.

The multifrequency mode can be applied to backscatter survey, offering the possibility to collect multifrequency backscatter data. The intensity of the acoustic response for each frequency is different depending on the type of sediment. By comparing these different responses, scientists can build an RGB map of the seafloor, which has been proven to be the first step towards bottom characterization.

Being able to survey at up to 5 frequencies in one pass and with a single MBES presents several advantages:

  • It increases productivity
  • It reduces the costs associated with traditional multifrequency surveys that require either multiple MBES or multiple passes
  • All 5 frequencies have the same grazing angle, which increases uniformity, accuracy, and precision

R2Sonic Products

We offer a simplified portfolio of 4 MBES, all with wideband selectable operating frequencies. What sets R2Sonic apart is the ability to customize each sonar with any of our suite of revolutionary technical options. You can add any of these options to any sonar at any time. You can upgrade remotely from wherever you are, whenever you need.
