Section 6
Target Tracking and AIS
This section explains Target Tracking (hereinafter, referred to as target tracking or TT) and Automatic
Identification System (hereinafter referred to as AIS).
Use the target tracking function as your navigation aid. Final decision on the ship
operation must be made by the ship operator himself.
If you depend entirely on the information of the target tracking function for the final
decision on ship operation, an accident may occur.
An error may be contained in the vector, target value data and alarm indicated by the
target tracking function. Further, the target not detected by radar cannot be captured
or tracked.
If you depend entirely on the information of the radar for the final decision on ship
operation, such an accident as collision or stranding may result.
Simulation is a function for determining if the target tracking function is working
correctly or not. Accordingly, this function should be used only to check for the target
tracking function operation.
In particular, if this mode is used during navigation, a pseudo target will appear on the
radar screen and cannot be easily identified from the real target. This may cause
such an accident as collision. Do not use this mode during the navigation.
Target Tracking
This function calculates the course and speed of a target by automatically tracking the target's move.
This function enables the automatic acquisition of targets by using the automatic acquisition zone
function.
This function also enables the simulation of the ship maneuvering method to avoid collisions by using
the trial maneuver function.
Memo
If the mode is ground stabilization, SOG/COG used for own ship's information. If the mode is sea
stabilization, STW (speed through the water)/HDG (heading) is used for own ship's information.
Target tracking range is 32 NM. (Available all range scale)
For the details, refer to "6.5 Setting and Operating Target Tracking".
AIS
This function shows the target's information on the radar display, using other ship's information sent out
from the AIS unit.
For the details, refer to "6.6 Setting and Operating AIS".
