DANGER
Radio Frequency Radiation Hazard
The radar antenna emits the electromagnetic radio frequency (RF) energy which can be harmful,
particularly to your eyes. Do not look at the Antenna Unit from a close distance while the radar is
in operation, or expose yourself to the transmitting antenna at a close distance.
The distances at which RF radiation levels of 10 W/m 2 exist are shown in the table below.
DO NOT approach closer than 9.1m (Safety standard is 10 W/m2) when radar is transmitting.
NOTE: This value is applied when radar is installed in a public space. Value is defined as on
human body surface over a 6-minute period with the flux density averaged from the
measurement. Moreover, this measured value is measured by pointing the center of the antenna
towards a human. However this is the worst value, definition required by actual regulation is
written here as on safe side.

1. SYSTEM SUMMARY
RADAR (Radio Detection and Ranging) developed during World War II as a method to detect the
presence of ships and aircraft (the military considered weather targets as noise). Since WWII, there
have been many advances in radar technology (e.g., Doppler techniques). It is used on land, sea,
and in space for both research and operational needs.
1.1. Type of Radar Bands
There are several different categories according to the wavelength of using on radar in the world.
Type of bands are L, S, C, X, and K band.
L band radars: “L” for “long”. This band is mostly used for clear air turbulence studies. It
operates on 15-30 cm wavelength and a frequency of 1-2 GHz.
S band radars: “S” for “short”. It is not easily attenuated and is useful for near and long range
weather observation. It operates on 8-15 cm wavelength and a frequency of 2-4
GHz. Some weather services use it on a wavelength of just over 10 cm. The
drawback to this band of radar is that it requires a large antenna dish and large,
complex motors to power it. It is not uncommon for an S band dish to exceed
7.62 m in diameter.
C band radars: “C” for “compromise”. The dish size does not need to as large so it is more
affordable for TV stations. It operates on 4-8 cm wavelength and a frequency of
4-8 GHz. It is best used for shorter range weather observation because the
signal is more easily attenuated by dry weather and rain. The frequency allows C
band radars to create a narrower beam width using a smaller dish. C band
radars also do not require as much power as an S band radar.
X band radars: “X” is derived from the XX2 secret band. It uses smaller wavelength, is more
sensitive and can detect smaller particles. It operates on 2.5-4 cm wavelength
and a frequency of 8-12 GHz. These radars are used for studies of cloud
development because they can detect the tiny water particles and also used to
detect light precipitation such as snow. X band radars also attenuate very easily
so they are used for only shorter range weather observation. Also due to the
small size of the radar it can easily transported, like the “Doppler on Wheels”
radar. Most commercial airplanes are equipped with X band radar to pick up
turbulence and other weather phenomenon.
K band radars: “K” for “kurz (German for short). This band is split down the middle due to a
strong absorption line in water vapor and it is similar to the X band but is just
more sensitive. It operates on 0.75-1.2 cm or 1.7-2.5 cm wavelength and a
corresponding frequency of 27-40 GHz and 12-18 GHz.

1.2. Anatomy of Weather Radar
Antenna: The main purpose of the antenna is to focus the transmitted power into a small pencil
beam and also to receive and collect the returned signal.
Radome: Protects the antenna from high winds, dusts, and rain.
Sub reflector: Directs the signal from the transmitter onto the antenna and also directs the return
signal from the antenna to the receiver.
Receiver: Detects the signal returned from a target.
Transmitter: Generates the microwave signal at the correct phase and amplitude. For X-band
weather radar, the wavelength of the signal is approximately 3cm.

1.3. Mechanical Operation
This system observes the development of rain clouds outputs the intensity of precipitation, the
speed of rain clouds (Doppler speed) and observes rainfall phenomena. It is capable of high
resolution rain observation, rain cloud, precipitation density and speed observation. The
solid-state transmitter replaces previous aging devices such as a magnetron.
The area sampled by the radar increases with distance. The wider the beam the greater the
likelihood of sampling a mixture of precipitation types and also a greater the likelihood of
sampled both inside and outside a cloud. Obstacles can also block a portion of the radar beam
resulting in an artificially high power return.
NOTE: Required accuracy for leveling
Although 0.4 degrees is an acceptable
level, it may cause a 209.4m difference at
a 30km distance from radar. For best
target accuracy make mount level 0.0 to
0.1 degrees.
1.4. Multi-radar System
The single X-band weather radar can be difficult to avoid problems with blind areas due to
buildings, mountains or strong signal extinction by heavy rain.
Furuno provide multi-radar system that consists of three radar systems. While two radar systems
are detecting and tracking rain clouds and observing their movements, the other one is working as
RHI sector scan mode at high speed and cutting through the clouds to observe their internal
structures. It is very difficult to complete signal processing of all the radar systems on single PC
because of the CPU performance. Therefore signal processing is distributed among the PC of
each radar system, and all the data are gathered on the central PC and composited into one
synchronized image.

1.5. Side Lobe
The energy radiated from an antenna forms a field having a definite radiation pattern. A radiation
pattern is a way of plotting the radiated energy from an antenna. This energy is measured at
various angles at a constant distance from the antenna. The shape of this pattern depends on the
type of antenna used.
To plot this pattern, two different types of graphs, rectangular-and polar-coordinate graphs are
used. The polar-coordinated graph has proved to be of great use in studying radiation patterns.
In the polar-coordinate graph, points are located by projection along a rotating axis (radius) to an
intersection with one of several concentric, equally-spaced circles. The polar-coordinate graph of
the measured radiation is shown in Figure 1.7.
The main beam (or main lobe) is the region around the direction of maximum radiation (usually
the region that is within 3 dB of the peak of the main beam). The main beam in Figure 1.7 is
northbound.
The side lobes are smaller beams that are away from the main beam. These side lobes are
usually radiation in undesired directions which can never be completely eliminated. The side lobe
level (or side lobe ratio) is an important parameter used to characterize radiation patterns. It is the
maximum value of the side lobes away from the main beam and is expressed in Decibels. One
side lobe is called back lobe. This is the portion of radiation pattern that is directed opposing the
main beam direction.
The now following graph shows the rectangular-coordinated graph for the same source. In the
rectangular-coordinate graph, points are located by projection from a pair of stationary,
perpendicular axes. The horizontal axis on the rectangular-coordinate graph corresponds to the
circles on the polar-coordinate graph. The vertical axis on the rectangular-coordinate graph
corresponds to the rotating axis (radius) on the polar-coordinate graph. The measurement scales
in the graphs can have linear as well as logarithmic steps.
Beam Width:
The angular range of the antenna pattern in which at least half of the maximum power is still
emitted is described as a „Beam With”. Bordering points of this main lobe are therefore the points
at which the field strength has fallen in the room around 3 dB regarding the maximum field
strength. This angle is then described as beam width or aperture angle or half power (- 3 dB) angle
- with notation Θ (also φ). The beam width Θ is exactly the angle between the 2 red marked
directions in the upper pictures. The angle Θ can be determined in the horizontal plane (with
notation ΘAZ) as well as in the vertical plane (with notation ΘEL).
Main and Side Lobes (Minor Lobes):
The pattern shown in the upper figures has radiation concentrated in several lobes. The radiation
intensity in one lobe is considerably stronger than in the other. The strongest lobe is called main
lobe; the others are (minor) side lobes. Since the complex radiation patterns associated with
arrays frequently contain several lobes of varying intensity, you should learn to use appropriate
terminology. In general, main lobes are those in which the greatest amount of radiation occurs.
Side or minor lobes are those in which the radiation intensity is least.
Front-to-Back Ratio:
The front-to-back ratio of an antenna is the proportion of energy radiated in the principal direction
of radiation to the energy radiated in the opposite direction. A high front-to-back ratio is desirable
because this means that a minimum amount of energy is radiated in the undesired direction.

Figure 1.7 shows the high level echo that
appears side lobes.
 Azimuth direction:
Antenna side lobes show both P0N
(unmodulated pulse emission for radars)
and Q0N (frequency modulation within
each pulse) covered area.
 Range direction:
Pulse compression (Range) side lobes
show Q0N only. It improves sensitivity of
long pulse but increase bling range.
However this blind area can recover
using un- modulated pulse.
Pulse compression is useful for weather radar to increase the average transmitted power by
transmitting a longer pulse but without reducing the range resolution of the radar.
Side lobe suppression is helping to eliminate the problem. For a radar pulse signal after
compression, the narrower pulse main lobe is always accompanied by higher side lobes. So, all
pulse compression radars suffer from range side lobes which cause energy from strong
reflections to leak into adjacent range cells. High suppression of side lobes is not required in
some other non-meteorological radar, but is important for meteorological radar because weather
phenomena can have significant reflectivity gradients, and ground clutter echo can be much
larger than medium rain. Furthermore, the side lobes of strong signal will falsely be recognized as
an existence of small target. Therefore, range side lobes must be suppressed by a large amount
to prevent contamination in adjacent range cells.

1.6. Location of Radar Installation
1. Confirm the observed region in relation the topography features:
In this example the radar must cover an altitude of 1500 meters maximum and a 70km distance
radius within the rainfall forecast area. Therefore there should not be any structures or objects
higher than radar around the installation point.
2. When installing antenna on building rooftop or a tall tower in urban area.
Mount the radar on the stand or tower, NOTE: it must be higher than any surrounding
obstruction (building, structure) for proper radar operation. The tower must be designed
strong enough to withstand heavy storms, winds and severe weather conditions.
Also note that a crane or aerial work platform vehicle might be necessary to mount the radar
and install the tower. It is important to consider any additional space required for crane
operation during installation or repair.
3. Lightning protection and grounding considerations:
Provide a lightning rod near or around the radar area to improve lightning protection
performance based on JIS A 4201, JIS Z 9290 and IEC 62305. Refer to APPENDIX A.
The protection systems should include surge protectors/absorbers.
The grounding system will typically consist of an underground grid, radials, or rods which
provide a ground resistance of not more than 1 ohm. It should have a connection point at the
base of the tower. Refer to APPENDIX A for more detail.

4. Survey antenna surroundings:
Ensure no interference to any surrounding antenna (e.g.: Broadcast, mobile (cell) phone
station, radio, BS/CS, etc.) and no obstacles should be around the antenna.
Moreover, secure a service space of 1 m or more around the antenna. In addition, strong
reflections can damage the receiver if there are obstacles nearby.
5. Power supply requirements:
Radar needs 100VAC (up to 240VAC), single phase 50/60Hz with GND. The minimum electric
current must be installed for voltage used, 100V is 10A, and 240V is 4.2A.
6. Telecommunication line and internet requirements:
Use telecommunication line for transferring weather observation data and operating the radar
by remote. The minimum require continuous speed to transfer all data in real time is 8 Mbps
or faster. A wireless network may have enough speed for just operating the system but we
recommend you to use a fast speed network like a fiber optic network when possible.
7. Building/ground structure:
The installed location of the radar must have proper load bearing resistance and durability to
support a tower or stand. However a structural plan from a professional architect and any
required permits may still be required for building or ground installation of the radar
tower/mount.
8. Human health considerations:
Build the radar stand at least 2 meters high if the radar is installed where people have easy
access to radar. A sign board must also be placed at the entrance or ladder at radar access
point.
9. Heating and cooling system:
Air conditioning is necessary to keep temperature stability for the room/cabinet (rack) of DPU.
10. Pseudo echo:
Set the sector blank to the obstacle direction nearby. When transmitting in the direction of the
obstacle, some pseudo echoes will be indicated due to reflections, therefore set the sector
blank until the pseudo echo disappear.
Note: DO NOT look at the antenna closer than noted below while radar is in operation. This energy
can be extremely damaging to the human body, especially the eyes. Furthermore DO NOT
points the antenna at any individuals closer than noted below while transmitting.
* As shown in Installation manual preface warnings (Table on page i, Radio Frequency Radiation
Hazard), the danger distance of transmit radio wave is set to 10W/m2 value for safe standard,
therefore do not go closer than 9.1m to the radar.
1.7. Radar System Certificate
Most countries by law have specific certificates for operating radar as a radio station. The radar
frequency is in a shared radio spectrum with many other radio services, providing functions
ranging from air traffic control to amateur radio operations. Although the radio frequency spectrum
is not a physical resource, the use of a frequency at a given location usually precludes that same
frequency from being used by others in the same geographic area. This need to have exclusive
geographic use to prevent harmful interference has led to the current spectrum regulations and
established spectrum use rules. Such rules grant licenses for spectrum use, and partitioning of
spectrum for shared use between radio services.
These certifications are approved by the Ministry of Internal Affairs and Communications (Japan),
Federal Communications Commission (USA), or other agencies of the specific country. It is
important to apply when deciding the radar location because it will take time to get certification
approval. It sometimes takes up to a year.

1.8. Requirement of Calibration
Calibration is the activity of checking or measuring and comparing with a specific standard
reference instrument. It may also include adjustment of the system to bring it into alignment with
the standard.
1.9. Peripheral Devices
- External HDD (Hard Disk Drive): Useful for saving large amounts of data. Use USB3.0 device
type to transfer the data at high speed. Recommendations include using a 6TB storage device
to save around one half years data (compressed).
- UPS (Uninterrupted Power Supply): Avoid risk of DPU crash by instantaneous power failure
due to electric power company trouble, facility power or natural disaster such as
thunderstorms. When possible use an outlet ON/OFF type selection device that allows
individual device power to be set ON or OFF remotely via the internet.

*1) Basic length of cable between ATU and SPU is 5m, NOTE: there are 10m, 15m and 20m options.
These cables have extra length for inside equipment. (e.g.: 5m cable = 5m + approx.2m)
*2) Cut the tube into two pieces to adjust a length between ATU and SPU.
Note: For tower radar installations this depends on the overall installation environment and consultation
will be necessary.

3. PRIOR CONFIRMATION
3.1. Confirmation Items
1) The mount plate must be installed properly for Antenna Unit (radome).
2) Power cable (AC100V-240V) must be routed safely.
3) Power cable gauge should be selected depending on its length.
4) Frequency of AC power source must be 50Hz or 60Hz sine wave and single-phase current.
5) All engineers must wear safety appliances including helmet and safety shoes during an
installation of Antenna Unit. It is dangerous that antenna could hit an individual by turning.
6) Secure a service space of 1 m or more around the radome. In addition, strong reflections can
damage the receiver if there are obstacles nearby.
7) Set the sector blank to the obstacle direction nearby. When transmitting in the direction of the
obstacle, some pseudo echoes will be indicated due to reflections, therefore set the sector
blank until the pseudo echo disappear.
Note: DO NOT look at the antenna closer than noted below while radar is in operation. This energy
can be extremely damaging to the human body, especially the eyes. Furthermore DO NOT
points the antenna at any individuals closer than noted below while transmitting.
* As shown in Installation manual preface warnings (Table on page i, Radio Frequency Radiation
Hazard), the danger distance of transmit radio wave is set to 10W/m2 value for safe standard,
therefore do not go closer than 9.1m to the radar.
3.2. Power Equipment
1) This equipment requires 1KVA x1 power line with grounded outlet (3 pin type).
2) The AC power cable attached to the DPU power supply is shipped with items conforming to
the PSE standard (Japan) and UL standard (US). Please prepare the power cable according
to the safety standards of the area to be equipped on the customer side.
3.3. Measurements
Notice: Measure the main AC power before powering on the radar.

3.4. LAN Equipment
1) Use Cat5e (or better grade) of 100Base-Tx LAN cable for transferring data from the Data
Processing Unit to the output equipment.
2) Prepare a high speed broadband connection (approx.100Mbps) for remote maintenance
access.
*Low speed broadband may cause slow access on remote support system.

Note: Disable automatic sleep function (also called ECO mode). It
is unsuitable for weather radar and will cause data loss. This is
because is sleep mode initiates between data transfer intervals
data will not transfer. Also the DPU cannot wake storage device
from sleep mode. DPU would require restart before storage device
will recover from sleep mode.
Please refer to UPS, Router, and other equipment documents separately.

4. PRECAUTIONARY ITEM
1) Use only single phase 100-240VAC commercial power supply.
2) DO NOT overhaul or modify.
3) DO NOT work on during electrical storm.
4) DO NOT scratch, cut, forcedly bend, pull, twist, bundle, or damage the power cable. Also do not
put heavy items on top or around.
5) DO NOT touch inside equipment with a wet hand.
6) Connect ground conductor for equipment protection and electric shock prevention from lightning
induction and ground leakage.
7) Cleaning instructions: Use dry soft cloth to wipe the surface. If it is difficult to remove stains use
the cloth soak with a neutral detergent to clean surfaces. Please DO NOT use an alcohol or an
organic solvent (e.g.: thinner) to clean surfaces.
8) When install the radar stand, level of stand should be within ±0.2 degrees.
