Advances in sonar technology, data storage capacity and data acquisition and processing systems open up new application developments that may turn underwater acoustic systems into powerful tools for future marine research, marine resource and coastal zone management.

Recent advances include the following, amongst others:

• Video-like quality of forward looking sonar imagery


• Extreme resolution for bathymetric systems


• Raw data output and recording possibilities for the complete water column


• Ocean depth capability for high resolution sonars and hydrophones


• Easy and flexible implementation of new applications/algorithms in sonar processor systems

 RESON offers a whole range of multibeam sonars, singlebeam echosounders and hydrophones suitable for application development in fields such as:

Fisheries Research and Management

• High resolution imaging sonars for localisation, mapping and characterization of fish schools


• Raw data recordings for detailed backscatter analysis with possibilities for fish stock characterization and biomass estimation


• Behavioral studies of fish and fish schools under varying ambient conditions

Marine Wildlife Research

• Imaging sonar systems for “video-like”, behavioral studies of marine mammals and (diving) sea birds even under very harsh observing conditions.

Environmental Research and Monitoring

• Single and multibeam systems for seafloor and sediment characterization/classification


• High resolution imaging and bathymetric sonars for habitat mapping and monitoring


• Mapping of seafloor vegetation, shellfish populations, coral reefs etc.


• Monitoring of oil-spill plumes and similar

 Ambient Noise Measurements

• High quality hydrophones with sensitivity down to sea-state zero, line drivers, amplifiers and recorders for ambient noise measurements such as waves, rain, man-made noise, marine mammal communication etc.

 Marine Archaeology

• High resolution sonars for mapping and identification of sunken buildings, ship wrecks and other artifacts on the seafloor
