The user may select to present
associated targets (i.e. activated
AIS targets associated with
tracked Radar targets) as either
activated AIS target symbols or
tracked Radar target symbols.
Alternatively, activated AIS target
symbols representing associated
targets may be modified by
circumscribing a circle around the
symbols’ isosceles triangle.
Tracked Radar target symbols
representing associated targets
may be presented with larger
diameter circles (up to 5 mm),
modified by inscribing an isosceles
triangle inside the symbols’ circle.
The circumscribed circle and
inscribed triangle shall be drawn
using a thin solid line style with the
same basic color used for target
symbols.
Associated targets may be labeled
or numbered, as appropriate.
Alphanumeric text used to
label/number associated targets
shall be drawn with the same
basic color as used for target
symbols.
