2.4.3 Scanner installation position
1) Physical selection criteria
•
Install the scanner at the center of the mast on the keel line.
•
If the scanner cannot be installed at the above position for some reason, the amount of
deviation must be minimized. And, reinforce the mount base and the platform and take
precautions to protect the scanner from vibration and impact at the installation position.
To avoid the radiating section coming in contact with other installed objects while it is rotating,
ensure that there is at least 200 millimeters from the swing circle (turning radius) to other installed
objects (Fig 2-22). The swing circle of the JMA-7100/9100 radar's scanner is as shown in Table 2-
5.
