The C3D system produces simultaneous sidescan and high-resolution bathymetry data
using the SARA CAATI method of echo arrival angle estimation.
SARA CAATI (Small Aperture Range Angle and Computed Angle of Arrival Transient Imaging)
is a patented technique licensed to Teledyne 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
The C3D is available in towed, over-the-side mount, and AUV configurations.
In the towed version, there are multiple cables and cable lengths available.
The standard cable is the 100-meter CAT5 cable for short tows.
For longer cable lengths, the addition of a CL-160 ADSL high-speed communications
link is required.
