The system was first accepted into service in 1940 and 4,000 of this basic layout were delivered.ĭetails of the rotating quirl dipole. Würzburg used a 3 m (10 ft) paraboloid dish antenna, which could be 'folded' along the horizontal midline for travel on a wheeled trailer.

It had a maximum range of about 29 km (18 mi) and was accurate to about 25 m (82 ft) in range. The Telefunken team developed an accurate system based on a klystron microwave tube operating in the range of 54–53 cm (553–566 MHz)-an extremely short wavelength for the time-with a pulse length of 2 microseconds, a peak power of 7–11 kW and a pulse repetition frequency ( PRF) of 3,750 Hz. The resulting system, known as the FuMG 62, as well as the prototype system FuMG 39T Darmstadt were demonstrated to Hitler at Rechlin in July 1939.

Attitudes changed in late 1938, when a full development contract was received from the Luftwaffe. By the next summer, the experimental set-up had been developed into a prototype known as the Darmstadt, which offered a range accuracy of 50 m (160 ft) at 5 km (3.1 mi), not nearly enough for gun laying. By the summer they had built a working experimental unit in the 50 cm band that was able to generate strong returns off a target Junkers Ju 52. Management apparently felt it to be as uninteresting as Runge had a year earlier and assigned it a low priority for development. With Lorenz already making progress on early warning devices, Runge had the Telefunken team concentrate on a short-range gun laying system instead. The developers then went their own way and formed GEMA ( Gesellschaft für Elektroakustische und Mechanische Apparate) eventually collaborating with Lorenz on the development of the Freya and Seetakt systems.īy the spring of 1935, GEMA's successes made it clear to Runge that the idea was workable after all, so he started a crash program at Telefunken to develop radar systems. Wilhelm Runge, was unimpressed and dismissed the idea as science fiction. Hans Hollmann, an expert in microwaves, who informed them of their work on an early warning radar. Rudolf Kühnhold of the Communications Research Institute of the Kriegsmarine and Dr. In January 1934, Telefunken met with German radar researchers, notably Dr. Late in the war, the British introduced the first jammers using the more advanced angle deception jamming.

Using information from these components, the Royal Air Force introduced Window and a series of white noise radar jammers known as 'Carpet' to interfere with their operation. This culminated in February 1942 with Operation Biting, in which components of an operational A model were captured. The larger Würzburg- Riese (giant) was based on the D model but used a much larger parabolic reflector to further improve resolution at the cost of no longer being mobile.Īs one of German's primary radars, the British spent considerable effort countering it. The A models began entering service in May 1940 and saw several updated versions over the next year to improve accuracy, notably the addition of conical scanning in the D model of 1941. The first Würzburg was a transportable model that could be folded for transit and then brought into operation quickly after emplacement and levelling. There were two primary models of the system. It took its name from the city of Würzburg. Eventually, over 4,000 Würzburgs of various models were produced. Initial development took place before the war and the apparatus entered service in 1940. The low- UHF band Würzburg radar was the primary ground-based tracking radar for the Wehrmacht's Luftwaffe and Kriegsmarine (German Navy) during World War II.
