Step 2 Use the check box Auto adjust the Range to the view scale to centre
the radar overlay in ECDIS.
Slide r Sea Clutter
Keep adjusting slider, as possible, until sea clutter is no longer disturbing
the radar overlay.
During this adjustment, the radar targets must be clearly visible at any time.
Slider Rain Clutter
Keep adjusting slider, as possible, until rain clutter is no longer disturbing
the radar overlay.
During this adjustment, the radar targets must be clearly visible at any time.
Slider Gain
The gain slider adjusts the sensitivity of the radar display. If properly
adjusted, the gain control results in noise appearing as a light speckle
at the dim level.
This light speckle setting yields the maximum detectability of targets
against a noise background. If the Gain is set too low, weak or distance
targets could be missed.
Correlation
Scan To Scan
This process requires three complete antenna rotations or scans of the
antenna to build up or decay detected targets.
To the operator, this means that when a target is firstly detected, it is
painted dim.
If on the next scan it is still present at the same location, it is painted at mid
level and on the third scan, it is painted bright. As long as the target is
present, is will paint bright. If the target fades in and out, then it will remain
on the screen, dropping from bright to mid and back to bright. If the target
is lost altogether, then it will take three scans before it completely
disappears.
