DEBUG AND SIMULATION FACILITIES
4.2 Rev. E
• Gyro,
when this function is selected, the gyrocompass function is
simulated
.
The adjacent window serves to vary the angle between the
ship and geographic north.
•
Video:
selecting this window reproduces the interferences and
background noises relevant to the situation to be simulated
.
• Tracking:
video simulation of a maximum of 40 targets to test the
tracking function.
Video Selection.
This facility is used only to make some test in the system and is strictly
recommended to return it back to the "Raw Video" at the and of the test.
• Raw Video:
Is the normally presented video.
•
Quantized Video:
It is the on-off video used by the ARPA to make the
tracking. Could be necessary to visualize the Q.V. to see if the ARPA sees
all the echoes and if the Q.V. threshold is correctly adjusted or if the auto
adaptive one works at satisfaction. To understand if it is working fine there
should be all the echoes visible in raw video plus some noise points
around.
Figure 4.1.2 Video view
•
Video Plot:
On the PPI will be displayed only the video of the plotted
targets. Could be necessary to use it to when the ARPA loses an
acquired target, to see if under the plot is present under the acquired
target.
WARNING
THAT THIS IS NOT THE SAME AS MANUAL SPEED, THIS IS A SIMULATION AND IF
YOU CHOOSE THIS FACILITY THE SYSTEM WILL ALSO STOP TO LISTEN TO THE
EVENTUAL EPFS CONNECTED AND WILL CALCULATE THE SHIP POSITION
USING THE SPEED YOU INSERTED.
