Figure 28 – Advanced Options Box
Advanced Options:
The Advanced Options will need to be changed during the
Commissioning. These are accessed through the System Configuration
Utility.
Default values for the Advanced Options are:
Minimisation:
4000
Clutter:
0
Mapping Beam width: 10,10 (99 degrees)
Interference Filter:
Disabled
Aeration Filter:
Disabled
Noise Filter:
Enabled
Minimisation
- Minimisation describes the filtering process used to
hide side lobe signals. Side lobe generated signals show up as a ring
on the sonar when a strong signal is received e.g. the seafloor.
See
Commissioning Step 11
.
Clutter
- Clutter describes the filtering process used to remove all signals
below a certain amplitude on the sonar and fish finder displays.
Set to
zero for Commissioning Step.
Beam width Reduction -
Reduce the beam width to improve the quality
of the sea-floor maps if the outer beams show errors due to water
refraction problems or shading of the transmitter beam pattern by the
ships keel.
Interference Filter
- The Interference Filter enables reduction in
interference caused by other acoustic devices such as sounders. It also
provides some noise filtering. It is recommended that the interference
filter be left selected (ON) on if you have another sounder or sonar on
your vessel that operates at the same time as the WMB-160/80F. Best
results are achieved if all other sounders are turned off.
Set the Interference Filter Level to High when encountering strong
interference, and Low when the interference is weak.
Disable this
function for Commissioning Step 1-5.
Aeration Filter
- This function is used to reduce the effects of strong
signals which appear on only part of the receiver array. Air bubbles,
sudden impacts and some other sources of noise can be suppressed
using this function.
Disable this function for Commissioning Step
1-5.
Noise Filter -
This function is designed to remove low level electrical
noise early on in the processing pipeline. This function is very effective if
used in conjunction with the Aeration Filter (even when the Aeration filter
is on the lowest setting) for removing unwanted signals.
Disable this
function for Commissioning Step 1-5.
Tx Pulse Blanking -
This will remove noise which is constant across
the sonar display, such as transmit pulses from other acoustic sounder
equipment. Works just with the sonar display and single beam display.
