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.
Distance from Antenna
9.1m
Power flux density
10 W/m 2
WARNING

OUTLINE OF SYSTEM
This system observes the strength of precipitation, the speed of rain clouds (Doppler speed), and observes
phenomena of rainfall.
Notice:
1. Do not go around the antenna area.
2. While installing antenna on a rooftop of building in urban area, it must be installed in the safety area and
protected by a lightning rod(s) based on IEC 62305.
3. No obstacles should be around the antenna.
Safe distance:
- If H1 is taller than 1.9 meters, it is safe unless directly touching the antenna.
- If H1 is shorter than 1.9 meters, do not enter within a radius of 7.6 meters from the antenna.
Note: It based on the standard human height of 2 meters.
- Refer the Radio Frequency Radiation Hazard on page i.
Note: It is safe to follow this calculated value because it still has some extra safer margin.
e.g.: H2 (Height) = 2m,
d (Distance between center of the antenna and human) =6m, θ=2° (Minimum azimuth is -2°)
H2-0.6+d・tanθ = 2-0.6+6・tan2°=1.6095m<H1
Therefore, H1 (Height of radar stand) = 1.6m,

SYSTEM CONFIGURATION
The observation system consists of an Antenna Unit (radome), a Junction Unit, and a Data Processing Unit
(indoor unit) is shown below.
(1) Antenna Unit (radome)
Radome is to provide protection for enclosed physical environment. Inside the radome, there is the antenna
that rotates and radiates the radio waves. The radiated waves are backscattered by particles on the
propagation path, return to the antenna, and are processed by RF converter to transfer the signals to the
Signal Processing Unit.
(2) Signal Processing Unit (storage box)
Signal Processing Unit is stored in the storage box, and processes received signals digitally. The digital
processed signals are transferred to the Data Processing Unit via 1000Base-TX (LAN). This unit is a relay
point of LAN cable (1000Base-TX Cat5e or better, it is recommend to use STP (Shielded Twisted Pair)
instead of UTP (Unshielded Twisted Pair) and switches on the power of the ATU. Do not exclude them
because of CE and FCC registration reason.
(3) Data Processing Unit (indoor unit)
Data Processing Unit is displaying radar data and operates the weather radar.
User needs to prepare the external storage device for recording the weather observation data if necessary.
DPU has 3 ports for the dedicated LAN connections; ATU/SPU (LAN1), Internet (LAN2), and MONI-CON
(USB-LAN adaptor).
Note: Do not install any software into DPU because it will cause an out of system resource problem.

About antenna rotation:
Basically the antenna is rotating clockwise based on
the azimuth origin during PPI and Volume scan as
shown on Figure 2.1.
About shielding area:
There may be some areas where mountains or other
obstructions are blocking the radio wave of radar.
RainMap indicates those areas with a gray color.
First the “Clip_RainMap.csv” file that describes the grayed
out area must be created.
Refer to quality information of observing data about scn
format in section 3.2 for detail of shielding area.
Shielding area data file format (see Figure 2.3):
The file format of shielding area uses a comma separated CSV file.
The first row is the header and below the first row will be the parameters.
Shielding area file name must be “Clip_RainMap.csv.
Header (reference and formula values):
Each column of header (red frame of column 1 to 4, row 2 in Figure 2.3) indicates an individual
parameter for the shielding area file.
Column 1: Distance value (m) used for shielding area range (distance) row cells calculation in “csv” file.
Column 2: Radar latitude in “clip_RainMap.csv” file must be entered as a decimal number, north latitude
is positive and south latitude is negative.
Column 3: Radar Longitude in “clip_RainMap.csv” file must be entered as a decimal number, east
longitude is positive and west longitude is negative.
Column 4: Radar altitude, entered in meter units for the “clip_RainMap.csv” file.
Note: Latitude, longitude, and altitude have to exactly match the values entered in “Radar Site Location”
settings in RainMap.
Parameter (values used in shielding calculations):
Let’s consider the column direction of parameter (green frame of column 1 to 720, row 3 to 11 in Figure
2.3) as azimuth direction, shown as 720 columns of 0.5 [deg] units. Rows denote individual distances
(range) direction and then the scan range of radar is divided by distance resolution and is the number of
rows. It needs to consider beam width when generating shielding area from digital elevation map.

In Figure 2.4, a building exists at a 5,000m distance from radar and in the azimuth area between 30 to
50 degrees. The building also shields the first 10 degrees of the radar’s elevation. Therefore the file
needs 10 degrees of elevation entered in each distance cell to 5,000m (100 x 52 rows) and each
azimuth cell between 30 to 50 degrees (columns 61 to 100) in csv file.
Also a mountain exists at a 10,000m distance from radar and in the azimuth area between 20 to 60
degrees. The mountain also shields the first 20 degrees of the radar’s elevation. Therefore the file
needs 20 degrees of elevation entered in each distance cell to 10,000m (100 x 102 rows) and each
azimuth cell between 20 to 60 degrees (columns 41 to 120) in csv file. Somehow it has to work on
manually.

reflecting the changes in the scan setting while observing.
Scan mode:
Select the scan mode of antenna. For PPI and
Volume scan modes. It is recommended that an
azimuth direction rotation speed of less than 7.0
[rpm] to maintain observation accuracy.
PPI scan [2D data]
[Plan Position Indicator scan]
Maintains a continuous equiangular 360 degree horizontal rotation at a single selectable elevation. It is
used to observe one set elevation continuously in a 360 degree radius.
Example of Setting:
To observe a 3.5 [deg] elevation angle at a
rotational speed of 7.0 [rpm] in a 360 degree
azimuth radius set as shown in Table 2.2.

Scans vertically (RHI) while moving horizontally, continuously within a preset azimuth and elevation
range generating a 3 dimensional rectangular solid angle. Horizontal data is not saved.
It continuously moves between the preset clockwise and counter clockwise azimuth and horizontal
limits.
Example of Settings:
The RainMap setting should be entered as
shown in table 3 to observe the parameters
shown below:
Elevation angle: 3.5 to 22.0 deg.
Range of azimuth angle: 30.0 to 60.0 deg.
Azimuth direction: 2.0 deg. (6.0 rpm interval)
Volume scan [3D data] (Refer to Figure 2.7)
This mode activates PPI scan to change the
elevation angle up to 32 steps. It references the
Volume Scan Period and RainMap time
indication.
Volume Scan is an observation of the azimuth
rotation speed and multiple elevation angles as
one complete pattern. Observation starts at the
specified minute (0 second) of every set interval.
Whatever set operation interval is used, all
selected steps must be completed within the
specified interval time. These volume scan
periods include, 1 (60 / [h]) 1 minute, 2 minutes,
3 minutes, ..., 2 (30 / [h]) 2 minutes, 4 minutes, 6
minutes, etc. Therefore, it is necessary to
consider the elevation angle value, observation
rotation speed (rpm), moving speed to elevation
direction (rpm), time to stabilize after elevation
change (fixed at 10 deg.), and observation
interval for setting.
For example setting will fail with following settings. 6.0 rpm azimuth rotation speed for 6 rotations in
one minute would seem to be a correct setting when observing 6 elevation angles with 1 minute
intervals (setting the operation interval to 1 (60 /
[h]). However in Volume Scan, movement occurs
in the elevation direction and does not display
while moving from one elevation to the next
elevation Because of the additional time required
for these elevation movements the above
observation scenario of 6.0 [rpm] AZ rotation
speed cannot be completed within the 1 (60 / [h])
volume scan period.
Example setting:
When observing these 6 elevation angles (3.5 /
5.5 / 9.0 / 12.0 / 16.2 / 22.0 [deg]) every one
minute, they can observed within a 58 second
period by using settings in Table 2.4.
(Rotation set to 7.0 [rpm] in azimuth direction)
Note 1: The ending time of scenario will be
different if elevation angle [deg] is
different even when using the same (0
to 5) elevation numbers.
Note 2: Elevation movement azimuth rotation
speed [deg] is fixed at 6.0 deg.

Note 3: When elevation movement mode is set to "AUTO" the upper limit value of elevation
movement speed can be set to 6.0 [rpm]. After the observation of one elevation angle the
movement to the next observed elevation can be completed faster. It is possible to select
"MANUAL", but "AUTO" setting is recommended.
Sector PPI scan (Refer to Figure 2.8)
[Sector Plan Position Indicator scan]
Scan horizontally within a preset azimuth area while changing elevation based on up to 32 possible
values generating a 3 dimensional rectangular solid angle.
