2.Installation of Scanner Unit > 2.4 PRECAUTIONS
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 2-15 Installation of scanner). The swing circle of the JMR-7200/9100 radar's scanner is as
shown in Table 2-5 Swing circle. See “SN.1/Circ.271 6.2(b)”.

2.Installation of Scanner Unit > 2.4 PRECAUTIONS
•
Avoid having a rope or signal flag from winding around the radiating section thereby
preventing it from rotating.
•
•
Avoid the effects of dust and heat caused by smoke from a chimney.
•
Provide for maintenance space: platform, safety link, hand rail, steps, etc. The lower
edge of a radar antenna should be a minimum of 500 mm above any safety rail. See
“SN.1/Circ.271 6.1(b)”.
•
When installing the scanner, select a location where there are the fewest structural
objects in the surrounding area so that the capability to drive the motor will not be
depressed by the non-equability wind which is likely to rotate the scanner.
When determining the appropriate scanner height and installation location, take into
consideration the reduction of vibration, the strength of the hull and the scanner mount
base, and maintenance properties.
2) Electrical selection criteria
•
The installation height of the scanner relates to the maximum detection distance. The
higher, the better. However, if it is too high, radio wave energy greatly attenuates
above the scanner's vertical beam width (the point -3dB from the peak of the main
lobe). As a result, it is difficult to detect a close-in target. Sea clutter also increases.
Determine the installation height by taking into consideration the weight, maximum
length of the cable, and maintenance after installation. See “SN.1/Circ.271 6.3(b), 7.1”.
•
If the installation height of the scanner is low, it is difficult to detect a long distance
target. The ship's mast, derrick, and chimney interfere with radiating beam causing
the range that cannot be viewed on the radar display to increase.
Generally, the lowest scanner installation position is supposed to be on the A-B line shown in
Fig 2-16 Lowest scanner installation height.
In the case of the JMR-7210/7225/9210/9225 type radar, 2θ equals 20 .
In the case of the JMR-7230/7272/7282/9230/9272/9282 type radar, 2θ equals 25 . Specifically,
the scanner position is normally elevated so that the chimney and the shrine-gate type mast do
not interfere with radiating beam.
The A-B line, or L line of sight from the radar antenna to the bow of the ship should hit the
surface of the sea in not more than 500 m or twice the ship length, depending which value is
smaller, for all load and trim conditions.
See “SN.1/Circ.271 6.3(a)”.

2.Installation of Scanner Unit > 2.4 PRECAUTIONS
• 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 2-17
Mounting rack and mast for the scanner). 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 meters 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 2-17 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 echoes 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 2-18 Scanner and the surrounding structural objects). See “SN.1/Circ.271 6.2(a)”.
Vertical beam width of X-band: Approx. 20
( 10.0
when the height of the radiating section is 0 )
Vertical beam width of S-band: Approx. 25
( 12.5
when the height of the radiating section is 0 )
Fig 2-18 Scanner and the surrounding structural objects
2-41
2.Installation of Scanner Unit > 2.4 PRECAUTIONS
•
When installing two or more scanners, scanners in close proximity should have a
minimum vertical elevation separation angle of 20 and a minimum vertical separation of
1m where possible, so that those scanners do not enter each other's vertical beam
width range. See “SN.1/Circ.271 6.1(c)”.
•
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. See “SN.1/Circ.271 6.1(a)”.
•
Keep a record of installation height data. The data is necessary for the initial setting
of the display unit.
•
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 2-19 Ensuring view angle).
Specifically, ensure a sufficient view field in the straight front (relative bearing 000 ).
See “SN.1/Circ.271 6.3(c)”.
•
Individual blind sectors of more than 5, or a total arc of blind sectors of more than 20,
should not occur in the remaining arc, excluding the arc in Fig 2-19 Ensuring view
angle. See “SN.1/Circ.271 6.3(d)”.
•
For radar installations with two radar systems, where possible, the antennas should be
placed in such a way as to minimize the blind sectors. See “SN.1/Circ.271 6.3(e)”.
Fig 2-19 Ensuring view angle
•
Magnetron which has strong magnetic force is included in the scanner. Install the
scanner at least 6 meters away from nautical instruments including magnetic
compasses and chronometers. See “SN.1/Circ.271 6.2(c), 7(c)”.
2-42
2.Installation of Scanner Unit > 2.4 PRECAUTIONS
*If there is a concern that structural objects existing within the vertical beam width may generate false
echo, 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.
When the structural objects exist in the surrounding area of Scanner unit, the false echo may appear.
The sector blank function is effective to reduce the signal reflection from the structural objects. Because
it can stop transmission. Therefore, it may reduce the false echo appearance.
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.
When the sector blank function set to on, ensure a sufficient view field in the straight front.
*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.
2.4.4 Confirmation during test run
If the scanner vibrates a lot during test run, try to reduce or prevent vibration by reinforcing the
scanner mount base or using wire stays attached to the radar mast.
2.4.5 Others
•
The design of the mounting platform for the scanner should take into account the
vibration requirements of resolution A.694(17) and furthermore defined by IEC 60945.
See “SN.1/Circ.271 7(d)”.
Vibration 2 to 13.2Hz
Amplitude
13.2 to 100Hz Acceleration
+/-1mm +/-10%
7m/s2
•
All installations should facilitate protection of equipment, including cabling, from
damage.
•
The cables should be kept as short as possible to minimize attenuation of the signal.
See “SN.1/Circ.271 7.2(b)”.
•
Crossing of cables should be done at right angles(90°) to minimize magnetic field
coupling. See “SN.1/Circ.271 7.2(e)”.
•
Eliminating the interference on frequencies used for marine communications and
navigation due to operation of the radar. All cables of the radar are to be run away from
the cables of radio equipment. (ex. Radiotelephone. Communications receiver and
direction finder, etc.) Especially inter-wiring cables between scanner unit and display
unit of the radar should not be run parallel with the cables of radio equipment. See
“SN.1/Circ.271 7.2(h)”.
•
Cable, coaxial cable and flexible wave guide should not be exposed sharp bends. See
also section 2.4.2 (4) “3) Permissible bending radius”. See “SN.1/Circ.271 7.2(g)”.
•
The grounding of equipment units should be carried out according to 0
