Chapter 1 INSTALLATION
14
When installing two scanners, provide a height difference so that those two scanners do not enter each other's
vertical beam width range.
To avoid interference with other equipment and to prevent radio noise from generating, do not place the VHF
antenna, GPS antenna, and INMARSAT's dome within the range of the vertical beam width. Keep a record of
installation height data. The data is necessary for the initial setting of the display unit.
Magnetron which has strong magnetic force is included in the scanner. Install the scanner at least 3 meters
away from nautical instruments including magnetic compasses and chronometers.
1.3.5 ENSURING VIEW ANGLE
Minimize the blind sector, and ensure the adequate view angle so that the blind sector does not exist in the
range 22.5° from side to rear (Fig. 1-3-5).
Specifically, ensure a sufficient view field in the straight front (relative bearing 0°).
Fig. 1-3-5
Reference:
If there is a concern that structural objects existing within the vertical beam width may
generate false images, equip the structural objects with a radio wave absorber.
(There are two types of absorbers: broadband type having no specific resonant frequency
and narrowband type which can absorb a band with a specific frequency. Use those where
applicable.)
Furthermore, it is effective to install a metal reflector, which reflects radio waves upwardly,
between the scanner and a structural object so that the radar's radio wave will not directly
come in contact with the structural object
Because most radio wave absorbers have poor durability, some must be replaced
every year.
When installing a reflector, the area to the rear of the reflector becomes a blind sector.
Therefore, minimize the size of the reflector.
The above procedures for selecting an scanner installation position are described based
on the radar's scanner. Comprehensively select the scanner position by considering other
scanners' installation procedure manual, hull's structure, strength of the selected position,
and vibration.
