Anchor watch
The Anchor Watch is a Radar Target only function, and it can be used when own ship is at
anchor and it is needed to monitor if it moves excessively from its original position.
To activate the function, proceed as follows:
1.
Acquire a completely stationary echo (i.e. a buoy).
2.
Select the target when its steady and press “Anchor Watch Off”, the target symbol will become
an anchor with a square around (selection) and the button will show “Anchor Watch On”.
3.
Placing the cursor on the spin box next to the Anchor Watch button, the help line will give
suggestions on how to change the Anchor Watch Range, which can be set in a value be-
tween 0.1 and 1 NM.
With this function activated and correctly set, the system will give an alarm (visible and also
audible if the audio is activated) if own ship moves outside the radius of the desired maxi-
mum range from its original position.
Training target
This function can be used to train the operator on manual radar target acquisition, selection
and tracking procedures, furthermore, it is a reliable tool to test the tracking facilities.
To activate this function, set the Training button to On and a simulated target will be shown
as a small “x”. The training target speed can be changed by means of the SKs placing the cur-
sor on the relative spin box next to the Training On/Off button.
The target starting position is 6 NM with a CPA of 0.5 NM and the TCPA depends on the speed
of own ship and the training target speed. Note that the training target speed is imposed only
at simulation start-up (it has no effect if it is changed with the training already on).
Activating the function, a big symbol “X” flashing at the lower part of the PPI warns that the
training simulation is running. From now on, the operator can perform all the tracking opera-
tions on the synthetic target (small “x”). Once the target has been acquired, the operator
should check that the characteristics of the target are:
•
Speed:
as set in the related field (True Speed) with a course of 180 degrees relative to the
course of own ship.
•
CPA:
0.5 NM
To disable the simulation, switch the Training button to Off.
The CPA and TCPA of the training target is automatically tested for accuracy by the system.
When the CPA becomes less than 0.25 NM or more than 0.75 NM, an alarm “Training Tgt CPA
Out of Range” is displayed. When the absolute difference between measured TCPA and calcu-
lated TCPA is more than 30 sec, an alarm “Training Tgt TCPA Out of Range” is displayed.
Cancel ALL TGT
This is a radar target only function, which allows the operator to cancel all acquired targets. Once
pressed, a new window will be displayed, asking to confirm target deletion or not. If the operator
presses “YES”, all the targets will be cancelled from the system. Otherwise no action is taken.
