Details:
Benthos has been a pioneer in the development of underwater acoustic and side scan sonar systems. Now Benthos combines high resolution side scan imagery with bathymetric data to produce a 3-dimensional look at the seafloor. The C3D is manufactured to the highest quality and reliability that one should expect in the offshore environment. The C3D represents the latest in sonar technology with patented technology that incorporates a multi-array transducer and solving for multiple angles of arrival for a 3-D image.
SARA CAATI (Small Aperture Range Angle and Computed Angle of Arrival Transient Imaging) is a patented technique licensed to Benthos by Simon Frazier University. It is a method for estimating the backscatter arrival spectrum. SARA CAATI uses an angle-of-arrival estimation similar to interferometry. However, unlike interferometry, the C3D solves the problem of concurrent arrivals from multiple angles.
The C3D is the best solution for combining side scan imagery and bathymetric data. The data sets are collected at the same place and time and there is no need to merge data sets as with multi-beam and side scan sonar systems run separately. Each point along the track has X, Y and Z components. For example, at the 100 meter range there are 2000 points compared to only a few hundred using multi-beam systems. This allows for a much greater across-track resolution.
Configuration 2 has a tow vehicle with over 1000 meter cable. The Long Cable ADSL towed vehicle has a depth rating of 2000 meters.
