BATHYSWATH-2

Bathyswath-2 provides high-density bathymetry and sidescan seafloor imagery data across a very wide swath width, especially in shallow water. It is the next generation in a long line of tried and trusted interferometric swath bathymetry systems.

COMPARISON OF BATHYMETRIC SYSTEMS
Both the interferometric multibeams and beamforming multibeams measure range and angle to a series of points on the seabed. A beamformer mathematically forms a set of “beams”, and detects the range to the seabed in each beam. An interferometer measures the angle of the incoming sound wave fronts in a time sequence of samples. Slant range is obtained from the time of the sample and speed of sound.

A COMPREHENSIVE BATHYMETRIC & SEABED MAPPING SURVEY SYSTEM

BATHYSWATH is an interferometric, wide-swath sonar system for surveying underwater surfaces, providing co-registered, high-density bathymetric data and seafloor imagery. Processed data outputs include digital terrain models and sidescan quality seafloor images. It is equally well suited for use at sea, inland waterways and on lakes.
BATHYSWATH-SPLASH is available as standard 2-transducer and enhanced 3-transducer versions, whereby the latter configuration offers an additional profile along the path of travel giving very high data density in the nadir region.

Three frequencies (depth ranges) are available; 468 kHz (to 80 m water depth, 234 kHz (to 200 m water depth) and 117 kHz (to 350 m water depth).
BATHYSWATH has a compact, lightweight and uncomplicated design. As such, it is easy to mobilise and demobilise and can be supplied with an optional bow mounting kit for rapid and convenient deployment and recovery. It offers a neat solution for a trailer transportable survey vessel.
