1.4 System Features

The main features of the SeaBat 7125 ROV system are summarized below. Depending
on the feature package purchased

, all features may not be available (see

appendix

Feature Packages

Resolution:

Dynamic, focused beamforming maintains ultra-high resolution,

even at short ranges. A receiver sample rate of 34kHz provides
unprecedented range resolution and complements the narrow beam, thus
providing the user with ultimate data quality and resolution.

Fast Update:

The entire 128° (or 140°) swath is illuminated with a single

transmission at an update rate of up to 50Hz (range selection dependent),
maintaining 100% bottom coverage, even at high speed.

Depth Rating:

The SeaBat 7125 ROV is depth-rated to 6000 meters.

Data Output:

The SeaBat 7125 ROV exports the standard hydrographic

records of bathymetry, side-scan, and snippets as well as water column data
and other data for more scientific applications.

Beamforming:

The 7125 processor performs initial signal processing, a

combination of time delay and phase rotation beamforming.

Bottom Detection:

The special bottom detection algorithm uses a

combination of center-of-energy and phase-zero crossing algorithms to detect
the bottom in each individual beam with the highest possible accuracy.

Uncertainty Output:

Uncertainty is computed for each sounding and

presented graphically on various UI (user interface) displays.

Variable Swath Coverage:

This feature gives the operator control of the

swath coverage. It includes swath width settings ranging from 45º to 128º (or
140º) in increments of 5° as well as a choice of beam density mode.

Auto Pilot:

This feature allows for automatic update of certain sonar settings.

When Autopilot mode is initiated, the SeaBat analyzes bottom detection data
to determine the average bottom depth and maximum usable swath angle,
then optimizes the sonar settings accordingly consistent with a user-
configurable look-up table.

Real-Time QC Display:

The SeaBat 7125 ROV generates a real-time display

with an intensity image on a high resolution 19-inch LCD monitor. Overlaid on
this intensity image is the bottom detection display, giving the operator an
excellent QC (quality control) tool.

Equidistant Footprint Selection:

The SeaBat 7125 ROV offers the operator

a choice between 256 and 512 equiangular or equidistant beams with the
400kHz frequency. All four options are dynamically focused. The optional
200kHz frequency operates with 256 equiangular or equidistant beams.

Hardware Sync Pulse Out:

A TTL pulse (synchronous with the transmitter

pulse) is available from the 7125 processor.
