SYSTEM PERFORMANCE AND DATA TYPES

7 SYSTEM PERFORMANCE AND DATA TYPES
There are several factors that can have a significant effect on acoustic performance. For this
reason, product performance estimates are indicative of standardized conditions for
temperature, salinity, bottom type or target strength, sound velocity, installation type, and
assume no affect from adverse environmental conditions such as wind, precipitation, sea state,
ambient or traffic noise, refraction, temporal changes or other surface effects. (Read also
section 6 Active Sonar Usage.)
To determine actual in-situ performance predictions requires a site or vessel survey and
environmental measurements with performance modeling based on the resulting
measurements. Costs for this survey may be quoted as part of a contract or independently.
The SeaBat T-Series Subsea sonar system produces four types of data, bathymetry, side-scan,
snippets backscatter, and water column backscatter, suitable for the generation of high-resolution
hydrographic charts that exceed international standards.
A single transmission from the projector unit illuminates the entire swath on the seafloor. The
seabed return signal is received by the receiver unit, digitized, and transmitted to the SSP, where
it is formatted for data and display output. Sonar data is stored locally or displayed remotely via
the Ethernet connection TCP/IP connection (see section 4.3 Remote Operation).
A Windows®-based user interface controls the system, allowing the operator to select system
configuration, data output, and storage options. This also provides built-in test environment
(BITE) displays to assist the operator.
For available configurations, see e section 1.6 Available SeaBat T-Series Subsea Configurations.

Documentation):
