MARPA target symbols
The system uses the target symbols shown below.
Acquiring MARPA target. Typically it takes up to 10 full rotations of the scanner.
Tracking MARPA target, not moving or at anchor.
Tracking and safe MARPA target with extension lines.
Dangerous MARPA target.
A target is defined as dangerous when it enters the guard zone defined on the
radar panel.
When no signals have been received within a time limit a target will be defined
as lost.
The target symbol represents the last valid position of the target before the
reception of data was lost.
Selected MARPA target, activated by positioning the cursor on the target icon.
The target returns to the default target symbol when the cursor is removed.
Tracking MARPA targets

Position the cursor on the target on the radar image
2. Select Acquire targets from the menu

After your targets are identified, it may take up to 10 radar sweeps to acquire and then track
the target.
Cancelling MARPA target tracking
When targets are being tracked, the radar menu expands to include options for cancelling
individual targets or to stop the tracking function.
Cancel tracking individual targets by selecting the target icon before activating the menu.
Viewing MARPA target information
If the pop-up is activated, you can select a MARPA target to display basic target information.
Information for the 3 MARPA targets closest to the vessel is also displayed in the data bar.
When a target is selected, detailed information for the target can be displayed from the
menu.
You can display information about all MARPA targets by using the Vessels tool option on the
Home page.
MARPA alarm settings
You can define the following MARPA alarms:
MARPA target lost
•
Controls whether an alarm is activated when a MARPA target is lost.
MARPA unavailable
•
Controls whether an alarm is activated if you do not have the required inputs for MARPA
to work (valid GPS position and heading sensor connected to the radar server).

Recording radar data

You can record radar data and save the file internally in the unit, or save it onto a storage
device connected to the unit.
A recorded radar file can be used for documenting an event or an operational error. A logged
radar file can also be used by the simulator.
