5) Latitude and longitude will be displayed on the screen
graph.
-
Blue line means solar position and orbit.
-
Red point means solar position (atmospheric
refraction included in measurement) with current
time.
[Note: Red point will only indicate during daytime
and not available during night time]
-
The angle of current solar azimuth and elevation is
shown with the number of degree.
5.3.3. Antenna position analysis operation
1) Click "Antenna_pointing_Analysis.exe" on the DPU
desktop or installed folder to start software.
2) Drag & Drop the observed data folder icon (observed
from solar_position) into [Radar_data_path] or click
folder icon to choose the data folder.
3) Click [
] mark in the menu bar to start the program to
see a graph of observed data files (.scn, .rhi, .sppi).
(Refer to "Operator's
descriptions.
4) The right sample screen shot is a solar scanning result
using Sector RHI scan.
5) The [Spectrum] graph is the solar radiation intensity.
6) Graph of [Solar_Azimuthal_Angle] and [Solar_
Elevation_Angle] will be calculated in the value of the
solar altitude and azimuth during observed time.
7) It determines the precise antenna position by
comparing the peak of solar radiation intensity and the
calculated solar altitude value.
8) Figure 5.7 shows two or more observed measured
solar data points (All data must be acquired using
same scan mode).
9) The [solar vs. antenna] graph shows the Sector RHI
upward elevation point plot peak in blue color and the
downward plot peak in red color. (Antenna moves up
and down to scan solar radiation)
It is determined by solar radiation peak value that
estimated
spectrum.
It simply and precisely checks the antenna graph.
Sector PPI will rotate clockwise and counterclockwise during antenna scan.
10) Graph of [3D plot] displays multiple observed data. It can capture the solar intensity in 3 dimensions
using sector scan:
Color indicates solar radiation intensity / Horizontal indicates azimuth / Vertical indicates elevation.
