Lichtenstein radar
Lichtenstein radar was a German airborn radar in use during World War II.
Early Lichtenstein BC units were not deployed until 1942, and as they operated on the 2 m wavelength they required large antennas. By this point in the war the British had become experts on jamming German radars, and when a BC-equipped Ju 88 night fighter landed in England one foggy night, It was only a few weeks before the system was rendered completely useless. The Ju-88 had flown the wrong way against a landing beacon and landed in the UK by accident not realising the mistake until too late the crew did not have time to destroy the radar or the German IFF.
By late 1943 the Luftwaffe was starting to deploy the greatly improved Lichtenstein SN-2, but this required huge antennas that slowed the planes as much as 50 km/h. Jamming the SN-2 took longer, but was accomplished. A 9 cm wavelength system known as Berlin was eventually developed, but only in the very last months of the war.
De Havilland Mosquito night intruders were fitted with a device called "Serrate" to allow them to track down German night fighters from their Lichtenstein B/C and SN2 radar emissions, as well as a device named "Perfectos" that tracked German IFF.
