The approximate position of the antenna on the vessel must be set
in order to correctly position the vessel outline when viewing close
range settings. The PPI will be centered on the icon representing
the position of the antenna.
The antenna height is the height of the antenna above the water
line, when vessel is carrying a typical load. It is very important to set
the antenna height correctly as this will affect the sea clutter
function.
The antenna span is the total length of the antenna.
Adjust bearing alignment
This option is used to align the heading marker on the screen with
the center line of the vessel. This will compensate for any slight
misalignment of the scanner during installation.
Misalignment that is not corrected for will compromise target
tracking and can result in dangerous misinterpretation of potential
navigation hazards.
Any inaccuracy will be evident when using MARPA or chart overlay.
1
Point the vessel towards a stationary isolated object, or
towards a far range AIS target where the AIS icon matches
the radar echo.
2
Adjust the coarse and fine bearing alignment so that the
heading line touches the end of the selected object, or the
radar target matches the AIS target.
Ú
Note:
Adjustments to bearing alignment has to be done before
Use mast rotation is enabled.
