How to determine the site of installation
A radar's target detection capacity varies greatly depending on the fitted posi-
tion of the scanner. An ideal fitting position is a location high above the ship's
keel line where there is no obstacle all around the scanner. In an actual ship,
such an ideal location is limited by various factors. Therefore, consider the fol-
lowing suggestions when you determine the place to install the scanner:
A. 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, crating shadow zones or generating false echoes.
Therefore, do not install the scanner at such a position.
B. Install scanner forward away from obstacle
To avoid creating shadow zones or generating false echoes, install the scanner
at a position nearer to the ship's bow 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 obsta-
cles" described in section 1.13.1.
C. 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 smoke-stacks or heat from lamps.
D. Install the scanner away from antennas or other equipment
Install the scanner as far away as possible from the antennas of a direction
finder, radio transceiver, etc..
