Medium power radar

MPR with Radom Staff and Support Company 22 in Erndtebrück

MPR of the Dutch Royal Air Force

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):

designation	Location	Insinuation	use of	Use up
Headquarters and Support Company 22	Erndtebrück	Mission control area 2 (EinsFüBer 2)		January 6, 2014
Separated technical train 245 (AbgTZg 245)	Brekendorf		1972	May 12, 2014
AbgTZg 242	Visselhövede		1971	5th July 2013
AbgTZg 243	Auenhausen		1971	October 10, 2011
AbgTZg 247	Lauda		September 18, 1972	February 11, 2013
AbgTZg 248	Freising		1972	20th September 2015

The conversion of the MPR stations on sensors of the type Groundmaster 406F of the manufacturer ThalesRaytheonSystems was completed in, 2015.
