Chapter 1 OVERVIEW
The proper installation of the radar equipment is critical in ensuing its effective and
reliable performance as well as facilitating maintenance and repair. Carefully install the
radar equipment by following the procedures below.
Install the scanner as high as possible while taking the scanner's weight into
consideration.
It is preferable to install the display unit in the wheel house to facilitate observations.
Available cable lengths and types for installing the radar JMA-3300 are as shown in
the table below. Request an appropriate cable from JRC beforehand. A cable
longer than the sufficient length may degrade radar performance, so give it careful
consideration when planning the installation.

INSTALLATION OF THE
SCANNER
2.1 SELECTING THE INSTALLATION POSITION
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. 2.1-1). The swing circle of the JMA-3300
radar's scanner is as shown in Table 2.1-1.
Both side covers of the operating section are opened for maintenance. Therefore,
install it 200 mm or more away from the other objects.

NKE-2103-4/4HS (4 feet) 1,320 mm
NKE-2103-6/6HS (6 feet) 1,910 mm
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.
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.
Provide for maintenance space: platform, safety link, hand rail, steps,
etc.
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 -3 dB 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. 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. 2.1-1. In the case of the JMA-3300 type radar, 2equals 20°.
Specifically, the scanner position is normally elevated so that the chimney and the
shrine-gate type mast do not interfere with radiating beam.

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).

Fig. 2.1-4 Scanner and the surrounding structural objects
Vertical beam width of X-band: Approx. 20° (+/-10.0° when the height of the
radiating section is 0°)
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.
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. 2.1-5). Specifically,
ensure a sufficient view field in the straight front (relative bearing 000°).

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.
* 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.
Reference:
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.
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.

Others
The design of the mounting platform for the scanner should take into account the
vibration requirements defined by IEC 60945.
Vibration
Frequency 2 to 13.2 Hz
13.2 Hz to 100 Hz
Amplitude +/-1 mm +/-10 %
Acceleration 7m/s2constant
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.
Crossing of cables should be done at right angles(90°) to minimize magnetic field
coupling.
Install the radar cable as far as from the cables of other radio equipment in order to
prevent other radio equipment from interfering with the radar operations. Especially
inter-wiring cables between scanner unit and display unit of the radar should not be
run parallel with the cables of other radio equipment.
Cable should not be exposed sharp bends.
Ensure that the equipment is grounded.
After installation
After you have completed the installation work, make a installation report with your
signature and explain it to the customer.
Then request him to keep the report on board a ship.
The installation report is now available for download on the our Marine Service
Department website (https://www2.msd.jp/).

2.2 INSTALLATION PROCEDURE
WARNING
Keep away from a scanner when it is transmitting.
The high level of microwave is radiated from the front face of the
scanner specified below. The microwave exposure at close range
could result in injuries (especially of the eyes).
50W/m210W/m22.5W/m2
NKE-2103 n/a 26cm 123cm
Direct exposure to electromagnetic waves at close range will have
adverse effects on the human body. When it is necessary to get
close to the antenna for maintenance or inspection purposes,
make sure to turn the indicator power switch to "OFF" or "STBY."
Direct exposure to electromagnetic waves at close range will have
adverse effects on the human body.
When conducting maintenance work, make sure to turn off the
power and unplug the power connector J1 of the display unit so
that the power supply to the equipment is completely cut off.
Some equipment components can carry electrical current even
after the power switch is turned off, and conducting maintenance
work without unplugging the power connector may result in
electrocution, equipment failure, or accidents.
Precautions for transporting and storing the scanner
A scanner is a heavy load. Be very careful about handling it.
Do not allow the scanner fall on its side while it is stored or being installed.
Do not apply rope to the scanner in the way that squeezes or deforms the radiating
section.
When hoisting the scanner by a crane, do not hoist it by attaching a belt or a rope
only to the scanner's radiating section as shown in Fig. 2.2-1.
When lifting the X-band scanner (Fig. 2.2-2) :
Wrap a cloth around the scanner's support section located at the bottom of the
radiator, and then attach a belt to it to lift the scanner.

Fig. 2.2-2 X-band
Installation Procedure
Maintain a flat level surface on which to install the scanner.
Use sufficiently thick steel material and reinforcement material for the scanner's
installation surface (mount base) to reduce vibration and impact. Keep the mount
base flat and smooth.
If there is a partial gap between the mount base and the scanner chassis's legs, work
on the installation surface so that it becomes flat and smooth, or make adjustments
by inserting metal shims.
If a gap exists and the scanner is tightly clamped, the chassis will distort and become
damaged by vibration.
Avoid using vibration-proof rubber and resin
Do not insert an elastic body, such as vibration-proof rubber or resin, between the
mount base and the scanner chassis' legs. If rubber or resin is inserted, the amplitude
of vibration increases, resulting in the possibility of damage to the scanner.
Furthermore, if installation bolts become loose due to deterioration of rubber or resin,
the scanner may be damaged or fall from its mount.
Wrap a cloth

Installation and clamping method
Installation direction
Installation should be done so that the cable gland is oriented toward the stern.
Bolts, nuts and tightening torque to be used
Use stainless steel bolts for the scanner and uniformly tighten all of the bolts using
double nuts for each bolt so that the scanner will not become loose (Table 2.2-1).
Although the length of the bolt will differ according to the thickness of the mount
base, use a bolt long enough so that more than 4 millimeters of thread protrudes
beyond the double nuts after the double nuts have been tightened.
Table 2.2-1 Length of scanner mounting bolts and tightening torque
Thickness of Mount Base Bolt Torque (N-m)
X band 12 M10×55 (mm) SUS304 40
Use of washer and corrosion-resistant measures
At the location where a bolt's head or nut comes in contact with the scanner chassis'
legs and the mount base, insert a plain washer which fits the bolt; and, at the location
where the nut comes in contact with the plain washer, insert a spring washer, and
then securely tighten the nuts (Fig. 2.2-3).
To prevent corrosion due to the contacts between different metals, such as the
scanner chassis' legs, installation surface, bolts, nuts, etc., cover the bolt's head and
nuts with sealant (Fig. 2.2-3).
Grounding and corrosion-resistant measures
Do not install the scanner in place where puddles are often formed.
Ground the scanner chassis and the installation surface (hull) by using an earth line.
Apply sealant to the connection portion of the earth line to prevent corrosion and
damage by vibration (Fig. 2.2-4).
