SYSTEM PERFORMANCE AND DATA TYPES
NOTE
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 7125 SV2 sonar system produces three types of data, bathymetry, side-
scan, and snippets, suitable for the generation of high-resolution hydrographic charts
that exceed international standards.
A single transmission from the projector unit illuminates a 140° (or 165°) swath on the
seafloor. The seabed return signal is received by the receiver unit, digitized, and
transmitted to the transceiver, where it is formatted for display and data output. Bottom
detection bathymetry soundings, side-scan, and snippets are displayed locally or
exported via gigabit Ethernet using TCP I/P protocol
15
to an external data collection
system.
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.
