If it is considered that sufficient installation height cannot be provided when the
scanner is installed directly on the roof of the wheelhouse, use a mounting rack or
radar mast (Fig. 2.1-3). Normally, when the scanner installation height is less than 2
meters from the roof of the wheelhouse, provide a mounting rack assembled at an
angle frame to install the scanner. When the scanner installation height is 2 m or
higher from the roof of the wheelhouse, provide a cylindrical radar mast to install the
scanner. Consider the convenience of the service staff who take care of installation,
maintenance, adjustment, and repair of the scanner by providing adequate footholds
to the mounting rack and the radar mast.
Fig. 2.1-3 Mounting rack and mast for the scanner
When installing the scanner, select a location where there are the fewest structural
objects in the surrounding area so that false images which interfere with target
detection will not be generated by signal reflection from other scanners, deck
structures, and cargo. Only as a guide, note that structural objects should not exist
within the range of the vertical beam width (Fig. 2.1-4).
