Tracking | Argus Radar Operator Manual
Selecting the items of the list, the corresponding target will be selected. Closing the list, the
targets data window will be displayed. This means that it is possible to select more than one
item from this list.
The AIS list is a tool where the operator can take a quick look at the AIS situation around own
ship, and it can list targets farther than the maximum range scale of the radar. It is useful to
search a ship by its name and select it, so that it will be “highlighted” by the selected symbol
on the PPI.
TT target list
Pressing the TT list labelled button, the “Radar targets selection list” will be displayed. This
menu has exactly the same purpose as the AIS list; it lists all the radar tracked targets being
tracked and the list can be sorted by range, dangerousness or id number.
¼
Note: Radar tracked targets will be given an ID number in the order they are received. Switch-
ing off and on the system, or looking at another radar display, this number can therefore be
different for the same target.
AIS limit priority
The number of targets that can be processed and visualized is 300 CAT1/2 or 120 CAT3. The
AIS Limit Priority button function is used to set the priority mode which will discard the AIS
targets exceeding that limit. It is possible to set the priority by:
• RANGE Only the ones closest to own ship will be accepted
• DANGER Only the most dangerous will be accepted. Danger is evaluated according to a
weighted combination of CPA/TCPA and relative speed.
AIS filtering
The AIS filtering function is used to filter the number of AIS targets displayed. This function
can be useful to avoid any possible confusion caused by the excessive number of targets
visualized. Its important to note that even if AIS targets visualization is filtered, all the targets
received (even the hidden ones) will continue to be processed and analyzed. For example, if
an AIS target is not visualized, but it becomes dangerous, it will appear instantly on the PPI
area. The filter operates on the total AIS targets counter and the relative maximum capacity
alarm.
It is possible to filter the presentation by:
RANGE
By selecting RANGE, a menu will appear requesting to select the maximum
displaying range from own ship in NM. All the targets outside this range will
be hidden.
CPA By selecting CPA, a menu will appear requesting to select the maximum value
for the CPA in NM. All the targets outside of this range will be hidden.
TCPA By selecting TCPA, a menu will appear requesting to select the maximum
value for the TCPA in minutes. All targets outside of this range will be hidden.
CLASS A
Only the AIS targets of CLASS A will be affected by the filter.
