Medium power radar
The Medium Power Radar ( MPR ) is a stationary 3D radar device for air defense in the stacked-beam design. The operational user in Germany between 1970 and 2015 was the operations command service of the German Air Force . Other Luftwaffe radars are RRP 117 , HADR (radar) , RAT 31DL and GM 406F .
System description
The individual sensor components are housed in a multi-storey building. To achieve the required high frequency output power , a Klystron TV2030 is used which operates on the exceptionally high voltage of 265 kV. The antenna is covered by a weatherproof radome . It was developed from the French radar device TRS 2201 (THD 1955) especially for Germany. The six units stationed in Germany were built by the French manufacturer Thomson CSF (now Thales Group ) using assemblies from AEG- Telefunken and Siemens in the 1970s.
In the transmission part, the power is divided into several vertically staggered transmission lobes by distributing it to a number of vertically arranged horn antennas, which results in a Cosecans² diagram . In the case of reception, the twelve different reception signals, each corresponding to an elevation angle range, are compared and the elevation angle is calculated from this .
The radar antenna reflector is over 16 meters wide and around six meters high, with an area of around 96 square meters and a weight of over 3.8 tons.
Naming
Contrary to the name Medium Power Radar (i.e. a radar of medium power), this radar with an impulse power of 20 megawatts was by far the most powerful air defense radar in Germany.
Deployment in Germany
Six MPR radars were in operation in Germany. The MPRs were most recently subordinate to the Air Force Operations Management Service (EinsFüDstLw):
