H4i3 - interferometric side-scan sonar (ISSS)


H4i3 - high resolution interferometric side-scan sonar (ISSS).  
The main purpose of interferometric side-scan sonar (ISSS) is bathymetric 3D swath survey of underwater relief.
Additional features  of the interferometer are associated with the ability to acquire simultaneously with bathymetric survey the sonar high-quality image, which opens access to the capabilities of SSS:

  • search for objects at the bottom and in the water column,
  • scientific, engineering, ecological and other monitoring.

Sonar survey of the water area (acoustics + bathymetry) is carried out by a complex placed on Board of a moving carrier (vessel, boat, boat, etc.). The range of the studied depths varies from units to hundreds of meters depending on the frequency of the complex, which allows you to work on any rivers, lakes and offshore seas , oceans.
The ISSS on each side contains a channel SSS, and additionally two separate receiving channels. Receiving channels are passive location channels using "backlight" (receiving echo signals emitted by the SSS transmitting antenna) from the corresponding SSS transmitting channel. Joint processing of echo signals of several receiving channels taking into account their mutual phase relations allows to obtain information about the depth of the water area along the beam with high accuracy.


  • overview swath survey of the bottom , identification of relief features, various inhomogeneities, swath survey of water areas;
  • search for objects at the bottom and in the water column;
  • engineering and ecological monitoring;
  • ensuring the safety of navigation;
  • depth measurement;
  • sounder measurement , and sounder measurement with instrumental evaluation;
  • swath bathymetry.
