How to remove interference and vessel’s own noise from
the echograms
The
Active
sub–menu offers a dedicated filter to
remove interference and noise from your own vessel,
the
Ping-Ping Filter
. This procedure explains how to
activate this filter.
The following filter options are provided:
a
Off
No filtering
b

For the current echo to be shown, the same echo must be present in at least two of
the previous three pings.
c
2 of 2
For the current echo to be shown, the same echo must be present in both of the
previous two pings.
d
3 of 3
For the current echo to be shown, the same echo must be present in three of the
previous three pings.
This filter was originally developed for our sonars, but has also proven to be very useful
in other hydroacoustic systems.
