Understanding the most unique sonar from Teledyne Marine

The RESON SeaBat F30 sonar is a unique and highly capable sonar that provides simultaneous 3D Forward-Looking Bathymetry and 2D Imaging optimised for Uncrewed Underwater Vehicle (UUV) platforms. The unique features of the sonar include:

  • 200kHz forward-looking bathymetry (3D mode)
  • 635kHz high-resolution 2D imaging
  • Switching between forward-looking and imaging modes

The RESON SeaBat F30 sonar provides a unique combination of forward-looking bathymetry and high-resolution imaging enabling resolution to discriminate objects at long ranges for obstacle avoidance. The unique forward-looking seabed bathymetry enables UUV navigation on the fly and provides a unique quality gap-fill to the sides that can sensor suite. Co-registrations of imagery (alternating) and bathymetry allows precise relocation of imagery after a mission.

The sonar has recently been ported to the latest Reson platform – the T-Series platform – making it robust and cost-effective technology that is non-ITAR. This provides new acoustic arrays and electronics technology. The footprint of the receiver is reduced to almost half and the depth rating has been increased from 3000m to 6000m. The T-series processing provides improved imaging and a faster switch between forward-looking bathymetry and 2D imaging.

The 635kHz high-resolution 2D imaging provides 512 beams with a 0.6-degree centre beamwidth. The result is clean images due to low sidelobe levels.

The 200kHz forward-looking sonar is an interferometric processing sonar with 112 beams that provides bathymetric data ahead of an underwater vehicle. The sonar is not intended as a hydrographic sonar as it is not the primary application, the primary application is forward-looking bathymetry for UUV navigation.

Advanced users can access the 66,000 samples per second as a platform to develop applications using the Teledyne SeaBat 7K PDS format.
