DEBUG AND SIMULATION FACILITIES
4.3 Rev. E
In the picture the video plots are the yellow echoes under the tracks and there
are displayed the tracking windows also (the light brown rectangles).
• Video Test:
On the PPI will be displayed only the video generated by the
Training function, available in the ARPA and AIS Menu. It is interesting
to see it when using the Training function. In the picture is present a
flashing cyan drawn cross on the plot, this means that it is the training
target. The light brown rectangle is the tracking window, normally not
displayed.
• Anti Sea Clutter:
On the PPI will be displayed some concentric circles
filled with different levels of yellow colour, showing the intensity of the
threshold of clutter suppression, according to the used shape.
In the zone of the strongest yellow the anti sea clutter suppresses more video
than in the zone of the light brown. By increasing the STC control the circles will
enlarge themselves indicating that the clutter suppression is moved out in
range.
Tracking Window
.
By activating this control it will be possible to see the windows where the
tracking is looking for the plot. For more information regarding the tracking
windows refer to the Video Selection section and see the Video Plot and Video
Test pictures.
