A radar station is a building complex for operating a radar system , in particular as an air traffic control radar . Such systems are usually set up on mountain peaks or in an exposed location in a terrain in order to achieve the greatest possible range of the radar location .
The antenna systems of a large-capacity radar can be up to 20 m wide and are usually protected from the weather by a conspicuous, spherical radome (radome). Research and weather radar stations have smaller antennas.
The processing of the measurement data can take place in the station itself or - as with regional air traffic control - centrally for the entire national territory, which requires corresponding data connections.
A radar station usually includes:
- The building in which the radar system is installed. The antenna can measure a few meters to almost 20 meters and work as a primary and secondary radar .
- Weather protection for the antenna (the so-called radome)
- Crew accommodation for operating and maintenance personnel
- Telecommunication systems. Earth-based, but often satellite or directional radio
- Electrical operating rooms
- If necessary, emergency power generators and self-sufficient water supply
- Bunker systems for military use
- Bunker fire brigade for militarily important use
The periphery includes:
- Access roads
- Power connection
- Water connection and sewage connection
- Data line to the regional headquarters
- if necessary, a protective fence around the area of the station.
Larger radar stations in Germany
- Regional air traffic control : The most important radar systems are operated by Deutsche Flugsicherung GmbH (DFS). There are around 32 radar stations spread over the whole of Germany. The antennas are usually located on a radar tower and are protected by a large radome. The range is a few 100 km in each case and overlaps each other so that isolated failures cannot affect air traffic control.
- Local airspace control: larger airports have their own Airport Surveillance Radar with a range of around 50–120 km, which controls approach and departure flights (ascent and descent).
- Purely military radar stations for air defense and flight control
- Radio traffic partly with radar: Some television towers
- About 16 weather radars and some research and satellite stations .
Radar stations in Austria
- Air traffic control: 2 civilian large-scale air traffic control radars (Upper Austria, Carinthia)
- Close-range radars at airports, etc. a. Vienna, Linz, Salzburg (some radars have been (and are still) replaced by multilateration)
- Military airspace control: 3 stations of the Federal Army with a very long range (Lower Austria, Salzburg, Carinthia), further local radar stations
- Satellite station Graz-Lustbühel
- Radomes of some weather services.
Radar stations in Switzerland
- Air traffic control: Skyguide radar station near Boppelsen, Canton Aargau and Zurich
- Military airspace control: additionally with mobile radar stations
- Precipitation radars from MeteoSwiss .
