Note
:
Some location will be difficult to adjust an azimuth from map if none of the mountain or any ground
clutter is surrounding within 70km. But there might have a solution for example, if it is in a flat
country like Denmark, a water tower in Lund, and Sweden, it used -1 degree, 10 km range and was
able to detect coastline and the city boarders of Copenhagen.
5.3. Solar Position Simulator
After installed Radar that ATU has mounted
horizontally, the solar measurement will be necessary
to setup the azimuth offset correctly. If the elevation is
in a tilted state, the error will become larger on the
opposite side in the sun direction.
Right Figure 5.2 is an image of sun path. There are
some exception area where comes the polar night.
However refer this image to use the solar positioning
simulator.

This procedure requires administrative rights]
Directory:
Open [Control panel] -> [Time & Date] -> Change to correct [time & date] and [Time zone]
5.3.2. Solar positioning
1) Click “Solar position simulator.exe” to startup the
software.
2) Check the time indication
“UTC_Date(YYYY/MM/DD)”
“UTC_TIME(hh:mm:ss))”.
3) Check time setting of PC if incorrect
(Refer to section 5.3.1)
4) Input radar site latitude and longitude information in the
RainMap ([setting] -> [antenna]).
