2. Introduction
Eclipse is a 3D imaging sonar with 3D measurement capability. A single housing
incorporates transmit and receive multi-beam arrays.
Eclipse uses electronic beam-shaping technology, providing a high performance
imaging system which can be used in 3D Volume Visualisation and 2D
Forward Looking modes.
By electronically steering the beam, a volume is illuminated ahead of the sonar. This
is converted, in real time, into a full 3D image. 3D Volume Visualisation
provides a realistic graphical representation of scanned objects.
The sonar data can be motion-stabilised by taking in data from an external motion
or tilt sensor.
The sonar data is displayed as a depth palletised 3D volume, where colour represents
the difference between the seabed depth and the vehicle Central Reference Point
(CRP). Eclipse provides data stream logging and replay as well as having image
and volume data snapshot capability. Measurement tools provide range, bearing and
relative position to any acoustic target.
The Volume Visualisation has a mode which displays all the individual sonar
contacts as single points. In this mode it is possible to measure the 3D relationship
between two points within the volume.
In 2D mode the Eclipse sonar provides a high update rate which is used to provide
display outputs that can be composed of a number of different sonar images, providing
better display resolution and filter options such as persistence and movement
detection.
Software Version
This manual is applicable to Eclipse software version 2.16.

3. Installation
3.1. Cable Specification
The Eclipse system is supplied with two cables, both of which are terminated at one
end with a Teledyne Impulse MHDG 3#16 5#20 connector. The 5m cable has bare
ends for termination/splicing into the vehicle wiring. The 10m cable is terminated
with a Souriau connector which mates to the bench PSU and can be used for testing
the Eclipse independent of the vehicle wiring and power supply.
Note
The network signal cables inside the supplied cable are Shielded Twisted
Pairs (STP). If splicing to a connector whip that is not provided with
twisted pairs, it is important to keep the untwisted length to a minimum
(no more than 20cm). Long lengths might result in network losses or
communication failure.

Caution
Never try to make the Eclipse work down a long cable by increasing the
PSU output voltage above 28V DC.
