INSTALLATION
This section includes instructions for implementing a 4213C Hydrophone mounting assembly, making
proper attachment of the 4113C Deck Cable, and the Transceiver side panel interface connections.
Hydrophone bearing, X, Y, Z offsets and pitch/roll offsets are generally determined at the time of
installation. This section includes sample procedures for determining
NOTE:
EdgeTech cannot give an absolute installation procedure because
each vessel is different, therefore EdgeTech can only provide guidelines.
The hydrophone installation is critical to the operation of the BATS.
Hydrophone / Interrogator Installation
The most crucial element in the BATS’ performance is the manner and location in which the hydrophone
assembly is mounted on the vessel. When choosing a mounting location, the operator should be aware
that by nature, the BATS is an extremely sensitive Acoustic System. Hydrophone assembly must be
positioned to receive acoustic pulses coming from pinger, transponder, or responder during operation.
The hydrophone should be mounted as far as possible from noise sources, such as propellers, thrusters,
echo-sounder transducers, main engines, generators, and other underwater acoustic generating systems.
Ideally, the hydrophone should be mounted far enough from nearby reflectors to allow the direct arrival
of a signal from the acoustic source before a potential reflected signal arrives.
One meter
is the minimum
recommended distance between the hydrophone array and the nearest reflector (which is usually to the
vessel's hull or keel), shown in
. To ensure 360-degree coverage, it is important to keep the
hydrophone below the level of the vessel's keel.

Equation 1
System performance can be degraded by multi-path or underwater signal reflections and reverberation.
To minimize the possible effects of multi-path, choose a hydrophone location that is as far away as
possible from any surface that would make a good reflector of an acoustic pulse. Any hard plate or
structure near the hydrophone has the potential to reflect pulses into the hydrophone. The air-water
interface is also an extremely efficient acoustic reflector. Avoid any mounting locations that would place
the hydrophone in the proximity of bubbles. Contact
for additional
information on a specific installation.
