H2S was the first airborne, ground scanning radar system. It was developed for the Royal Air Force 's Bomber Command during World War II to identify targets on the ground for night and all-weather bombing.
An object at height h above the ground and slant range R forms an angle α that can be calculated through sin α = h / R.By re-arrangement, R = h / sin α, or R = h csc α. The radar equation states that the signal received from an object, P e, varies inversely with the 4th power of range and directly as the square of the antenna gain, G, such that P e ~ G 2 / R 4.
FuG 224 Berlin A, and the contemporary FuG 240 Berlin N1 or Nachtjagd air interception radar, [1] [2] both made use of captured examples of the British cavity magnetron in the H2S radar. A H2S-equipped Short Stirling bomber had crashed near Rotterdam on the night of 2 February 1943. [3] This led to H2S being given the German codename Rotterdam ...
III radars, which had been developed from the H2S equipment. This U-boat is equipped with the Fliege and Tunis antennas. The Naxos radar warning receiver was a World War II German countermeasure to S band microwave radar produced by a cavity magnetron. Introduced in September 1943, it replaced Metox, which
FuG 350 Naxos Z: The original system, detected H2S radar system on bombers. Unable to distinguish individual bombers nor the 10 GHz H2X Allied bombing radar, but could reliably guide the fighter into the bomber stream. FuG 350 Naxos ZR: Additional aerials added a tail warning system which allowed British night-fighters to be detected.
It was a development of the British H2S radar, the first ground mapping radar to be used in combat. [3] It was also known as the "Mickey set" [4] and "BTO" for "bombing through the overcast" radar. [5] H2X differed from the original H2S primarily in its X band 10 GHz operating frequency rather than H2S' S band 3 GHz emissions. This gave H2X ...
