3.5 Targets
ARPA and AIS targets can be displayed simultaneously on the PPI. In
some cases it is possible that one and the same object is tracked as
an ARPA target and also activated as an AIS target. If the ARPA and
AIS target have similar data for distance, course and speed, they can
be fusioned. This means that they are treated as one target as long
as the similarity is existant. The limits for the similarity of the data can
be defined by the operator. See chapter 3.5.1 on page III-59
In other cases it is possible that the two targets are treated as two
different objects.
Anyway under Fusion, the system can be set in a way that one type of targets has priority being
displayed. Nevertheless, both types of targets are still tracked or remain activated in the background.
Independent of the selected priority in the PPI it can be selected for an individual target which data and
graphics shall be shown. See chapter 7.2 on page A-59, "Reverse Fusion" for details.
Additionally it can be selected under Sleeping which type of sleeping AIS targets are to be displayed
continuously.
With the selection Trial the trial manoeuvre function can be activated or switched off. See chapter 7.12
on page A-72 for details.
