(Airborne Interception) – British night fighter radars |

(A.B.C.).– ARI TR3549 jamming transmitter |
BABS |
(Beam Approach Beacon System) ARI TR3567 - British blind-landing system |
FIDO |
RAF fog dispersal system installed at 15 RAF stations |
Flammen |
German plotting system for detecting Oboe-equipped Pathfinder Mosquitoes |
Freya |
British fighter warning radar add-on to H2S, fitted early 1944 to some bombers |
GEE |
German ground based air search radar |
Granite |
British radio navigation system forerunner of LORAN - from TRE. a system of coloured flares and rockets deployed by the Royal Observer Corps to warn aircraft of high ground in fog and mist. In certain parts of the country the flares were used to steer fogbound aircraft to FIDO equipped airfields. |
H.F.D.F. |
(High Frequency Direction Finding) – provided a radio position fix for the RAF up to 100 miles from the transmitters in Britain. The system was based on voice communications, and was used for aircraft to find their home bases. The development of GEE its primary function ceased but it remained in use until the end of the war as a backup system and a communications system between aircraft and their base. |
H2S |
British ground mapping radar to see target at night and through cloud cover |
Himmelbett |
German controlled night fighter method |
IFF |
Identification Friend or Foe (IFF) - means of identifying possible enemy aircraft detected on Chain Home early warning system using transponder fitted in RAF aircraft - from TRE |
Jay beams |
were introduced partly as a deception to help to confuse the Germans over the use of GEE. It was nevertheless just as useful as a homing beacon. A number of transmitters, from Lossiemouth to Manston in Kent transmitted on slightly different frequencies transmitted a narrow beam across the North Sea using a S.B.A. (Standard Beam Approach) transmitter, receivers for-which were fitted to all British bombers and could be received over a range of 350 miles at 10,000 feet. Once a bomber found a beam it could fly down it back to Britain. In late 1943, all but two beams were closed down with these final two shutting down towards the end of 1944 because GEE could do the job better and their use to deceive the Germans was by now redundant. |
M.F.D.F. |
(Medium Frequency Direction Finding) - provided a radio position fix for the RAF up to 230 miles from the transmitters in Britain. The system was based on voice communications. |
Oboe |
British twin beam navigation system, similar to Knickebein but pulse-based |
Bomber stream |
British tactic to overcome the Kammhuber Line |
Gardening |
RAF operations dropping mines in strategic sea lanes, usually at the request of the CoS Naval Liaison Officer based at High Wycombe. As a spinoff, Bletchley Park cryptanalysts used German reports of Gardening activities to obtain decryption information on Enigma transmissions |
Wilde Sau |
(Tame Boar) – German tactic of guiding a night fighter 'parked' round a visual beacon, onto the incoming bomber stream by radar assisted ground commentary |
Zahme Sau |
(Tame Boar) – German tactic of guiding a night fighter 'parked' round a visual beacon, onto the incoming bomber stream by radar assisted ground commentary. |
