Installing the Radar Base
A radar's target detection capacity varies greatly depending on the fitted position
of the scanner. An ideal position is a location high above the ship's keel line
where there are no obstacles around the scanner. On an actual ship, such an
ideal location is limited, therefore, consider the following suggestions when you
determine the place to install the scanner:
(a) Install scanner at a position as high as possible.
The higher the installation position, the longer the ranging distance. Install the
scanner at a position as high as possible after considering the ship's hull structure
and radar maintainability.
(b) Install scanner away from smoke-stack and mast
If the scanner is installed at the same height as the smoke-stack or mast, radar
waves may be blocked, creating shadow zones or generating false echoes.
(c) Install scanner as far forward as possible.
To avoid creating shadow zones or generating false echoes, install the scanner at
a position nearer to the ship's bow and away from obstacles. When installing the
scanner on a mast, position it in front of the mast (If obstacles cannot be avoided
for the ship's structural reasons, refer to "Shifting away from obstacles" described
below.)
(d) Do not install the scanner near hot or heat-generating items.
Do not install the scanner at a position where it may be subjected to smoke or hot
air from smokestacks or heat from lamps.
(e) Install the scanner away from antennas of other equipment.
Install the scanner as far as possible from radio antennas.
Warning
: Radar can effect and be effected by other antennas.
Ensure that your scanner is installed as far from other antennas
as possible.
(f) Make the cable length as short as possible.
Keep the distance from the scanner to the control box within the standard cable
length of 10 m. If you use longer cable for unavoidable reasons, limit the cable
length to a maximum of 100 m.
