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.

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.
