3 Azimuth
Set an azimuth difference between a tracked target and an AIS target to be identified as
one target. Set the azimuth range between 0.0 and 9.9 degrees.
A narrower azimuth range means a stricter condition.
The possibility of mistakenly identify resembling targets will be lower, but targets are less
likely to be identified as one target.
A wider azimuth range means a looser condition.
Targets are likely to be identified as one target, but targets with similar parameters are
likely to be mistakenly identified.
Adjust the setting in accordance with the intention.
(Targets that are judged to be identical will be indicated as an association symbol.)
(AIS target and tracked target are shown separately even though they are determined
to be identical.)
