Description
Use the
SR Receiver Filtering
functionality to minimize the
interference from other acoustic
systems (sonars and echo sounders)
on your own and/or other vessels.
The filter also suppresses noise
from your propellers, and from
other similar noise sources. The four
filter settings are used to control the
"efficiency" of the filter. To disable
the filter, set it to
Off .
Details
Interference Filter
The
Interference Filter
will
remove noise and false echoes
from other echo sounders and
sonars in the vicinity of your
own vessel. This is a median filter.
When you operate in areas with substantial reverberation due to the bottom
conditions, or in shallow waters, you may experience “jumps” or spikes in the
data received from the sensors. Such errors can also be caused by other types of
hydroacoustic equipment operating on the TV80 frequency range. This filter has
been implemented to remedy for such interference problems as well.
The
Interference filter
offers four different settings. The default setting of the
Interference Filter
is Weak .
• In Off mode, the filter is disabled.
• In Weak mode, the data from the last three sensor transmissions are median
filtered.
• In Medium mode, the data from the last five sensor transmissions are median
filtered.
• In Strong mode, the data from the last seven sensor transmissions are median
filtered.
