3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Clearance environment clearanceenvironment
When the weather radar is operating at the lowest elevation angle, the main beam of the antenna is not subject to occlusion.
Note. Rewrite GB 31223-2014, definition 3.10.
3.2
Electromagnetic environment electromagneticenvironment
The sum of all electromagnetic phenomena present at a given location.
[GB/T 4365-2003, definition 2.1]
3.3
Equal beam height map heightchartofiso-beam
In the standard atmospheric refraction, according to the occlusion of the ground around the radar station, the target of a certain height can be illuminated by the radar beam.
Large distance changes with orientation.
3.4
Obstacle obstacle
An object that obscures and affects high-frequency electromagnetic waves emitted and received by the radar.
[GB 31223-2014, Definition 3.3]
3.5
Occlusion elevation blockelevationangle
The angle from the lowest working elevation angle of the radar to the angle at which the lower edge leaves the obstacle, from the presence of occlusion to occlusion
The angle at which the lower edge of the beam rises when it disappears.
[GB 31223-2014, definition 3.5]
3.6
Occlusion azimuth blockazimuthangle
Obstacle occlusion of the radar beam, the orientation of the radar beam edge (-3dB) into the obstacle area, and the radar beam edge
