Low signal to noise ratio and signal to clutter ratio
In situations where the signal to noise or the signal to clutter ratio of
the radar echoes is low (small vessels in heavy sea or rain clutter, or
big vessels close to the radar horizon), target detection is poor and
the tracking will not detect the target at each antenna revolution.
This will cause errors in the tracking, and it can range from missed
information and up to complete loss of the target when it is missed
for 10 consecutive antenna revolutions.
Dangerous targets
Radar targets are defined as dangerous targets in the Vessels and
tracked targets dialog (TCPA/CPA settings), refer to
"Vessels and tracked
targets"
on page 134.
For the system to display dangerous target alert messages when
dangerous targets are detected, the Dangerous vessel option must
be enabled in the Vessels section of the Alarms settings dialog.
Dangerous target alert messages
When a vessel meets the dangerous target criteria set in the Vessels
and tracked targets dialog (TCPA/CPA settings) and if the
Dangerous target alert option in the Alarms settings dialog is
enabled, a dangerous target alert message dialog is displayed. The
following options are available in the message dialog:
