Wurzburg, FuGM 39/62
Short-range ground radar. Range 170km, frequency 560MHz, range precision 100m, angle precision 0.2 degrees.

Wurzburg A ordered by Luftwaffe leaves the factories of Telefunken to be tested the first time on April 9, 1940. It is a light radar of identification, of average range. It can detect and continue the planes to 25 km.
It is in summer 1941 that one will start to associate it other traditional radars:
Freya, rather similar with the machines combined, and intended to supervise a vast airspace (several hundred km).
With the approach of enemy planes, it warns FuGM39/62. Wurzburg hangs its prey then and directs the shootings of Flak on it.
Its characteristic is that it is the first so mobile radar, miniaturized as much, and directional with 360° by its system of rotation on 2 axes.

Five men are necessary to the operation of Wurzburg FuGM 39/62 :
«The B6 seated at the elevation quadrant passed the altitude information by voice radio to a command and control center or to an associated searchlight unit. Next to him, the B5 sitting at the bearing indicator instrumentation on by radio as needed. The B1 stands at the rangefinder, a cathode ray tube (CRT). Next to him is the B3 standing at the height tracking scope, while the B2 sits in the control seat, where he controls the elevation angle and bearing of the system. If the Übertragungsgerät 37 were not operating, the B4 would stand next to the B1 at the rangefinder to pass on ranging information via radio.»

Wurzburg will profit from many perfections to improve the precision and the automatic exploitation of measurements:
C-Zusatz on Wurzburg C in 1940, carrying an angular precision with +ou- 0,45° with a broader cover still.
The EAG 62 Emil equipping Wurzburg D in 1942, automatically transmitting the co-ordinates to the calculator of ordering of shooting.
