That's interesting. Reverse engineered from captured H2S radars? In which year?Basil said:[...]However it was not a night fighter radar but a surface surveillance radar like the British H2S from which it was derived.
Berlin A (FuG 244) [that should read FuG 224] was developed by Telefunken, based on captured RAF H2S and US AN/APS-13. First deployed early 1944; only approx. 50 units built. It embodies most of the PPI radar concepts still in use to this day. The polyrod antenna had the same pattern as a dish, but offered much less wind load. It was mounted in a low-loss composite radome on the airframe’s underbelly. The high rotation speed eliminated the need for a long-persistence CRT and allowed ambient-light viewing.

I think antenna-behind-nose-cover refers to the FuG 240 alone, not to the FuG 224.The FuG 224 and FuG 240 Berlin 9 cm (3.3 GHz) airborne radars were based on H2S, and used
captured examples of the British cavity magnetron. The parabolic dish antenna was installed inside
a streamlined nose cover. Between 30 to 50 were issued to service units, mostly on the Ju 88G-6.
That, combined with Justo's radome picture, should settle the question whether FuG 224 was a belly-mounted air-to-ground or nose-mounted intercept radar.4-element polyrod antenna, downwardlooking & rotating at 400 rpm.
Da das Gerät ursprünglich für die Luftwaffe entwickelt wurde, ist eine besondere Anordnung für die Höhenmessung über Grund vorgesehen. Diese wird für Marinezwecke nicht benötigt und deshalb nur beiläufig erwähnt.
Because the apparatus was developed originally for the Lufwaffe, a special provision is made for altitude-measuring over ground. This is not necessary for naval purposes, therefore mentioned only in passing.
