2.6 Simplified Target Tracking (TT)
WARNING
Do not rely solely on the Simplified Target Tracking (TT) feature for collision avoidance.
Always pay attention to your surroundings, including other vessels, obstacles, water and
weather conditions. Never leave the helm unattended. You are responsible for the safe
operation of your boat.
CAUTION
The tracking information, including the course and speed of acquired targets, depends
on the radar and the tracked targets. The radar must be tuned and functioning normally
to ensure the targets can be correctly identified and tracked.
Sea and weather conditions can affect target acquisition and target tracking. Adjust gain
and clutter reduction settings correctly to properly keep track of TT targets (see
2.4
).
Tracking accuracy can be affected by echo intensity, pulse width, bearing error, and
course change. The accuracy will decrease when either your boat or the target changes
course, and the restoration of the accuracy may take between 10 and 60 seconds,
depending on the relative speed between your boat and the target.
Simplified Target Tracking (TT) enables you to manually or automatically acquire and
track targets and is primarily used for collision avoidance. To use TT, you assign a TT tag
to a target. The radar then automatically tracks the tagged target and provides you with
tracking information about the target.
2.6.1 TT Features
• Targets in all ranges can be selected as TT targets.
•
Up to 50 targets can be acquired and plotted with adjustable vector time (
Projected
Heading
) on the screen (see
3.4.3

• Targets can be acquired automatically by using
Boundaries
,
MotionScope™
, or
Guard
Zones
(see
2.6.3
).
•
Collision alarm can be turned on for TT targets, with adjustable CPA limits (
Range
)
and TCPA limits (
Time To
) (see
3.5.1
).
•
Tracked targets can be canceled individually or altogether (see
3.4.1
).
