H2S
The H2S is an English onboard panorama radar (code name “Home Sweet Home”). It is fitted with a magnetron that produces a pulse power of P = 50 kW with a wave length of λ = 9.1 cm. Its parabolic antenna has horizontal polarization and rotates at 60 rpm. The panorama image is projected on a CRT. At a test flight in October 1941 a test device developed for night fighter planes shows a recognizable image of Southampton.
In August 1942 the device was ready for production and its prompt installation in bombers is ordered. During the night of 30/31 January 1943 bombers equipped with H2S radar are used as scouts of the attack on Hamburg.
