Rose Point Radar Installation Guide 3
Determining Installation Location
Scanner Unit
A radar’s target detection capacity varies greatly with the position of the scanner. An ideal position is a
location high above the ship’s keel line where there are no obstacles all around the scanner. In an actual
ship, such an ideal location is limited by various factors. Therefore, consider the following suggestions
when you determine the place to install the scanner:
1. Install scanner at a position as high as possible.
The higher the installation position, the longer the radio ranging distance. Install the scanner at
a position as high as possible after considering the ship’s hull structure and radar
maintainability.
2. 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. Therefore, do not install the scanner
at such a position.
3. 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 obstacles” described below.)
4. 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.
5. Install the scanner away from antennas of other equipment.
Install the scanner as far away from antennas of a direction finder, radio transceiver, etc. as
possible.
6. 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.
