*Bromide - British X-Gerät jammer
*Carpet - 100 Group W/T (morse radio) jammer
*Cigar (later "Ground Cigar") - earlier ground-based version of Airborne Cigar

Chain Homeradar - British land based early warning radarused during the Battle of Britain
*Düppel - German radar countermeasure called chaff in the US or window in England
*Darky - RAF a backup system in case the other systems were broken or the operator of the other direction finding systems was dead. Using his radio, on 6.440 MHz the pilot could be talked back to his home base.

*Domino - British Y-Gerät jammer - see also Benjamin
*Eureka - portable homing beacon system - ground transmitter - see also Rebecca
Fishpond- British fighter warning radar add-on to H2S, fitted early 1944 to some bombers
*Flensburg - German radar device fitted to night fighters that detected British Monica transmissions
*Freya - German ground based air search radar
*G-H - British radio navigation system used for blind bombing
*GEE - British radio navigation system forerunner of
*Grocer (later "Ground Grocer") - ground-based version of Airborne Grocer
*H.F. D/F (High Frequency Direction Finder ) [This RAF system was a different system from the better known Naval
Huff-Duffsystem.] - 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 back up system and a communications system between aircraft and their base.Harris [http://books.google.co.uk/books?id=jzzl8wUn52cC&pg=PA194&lpg=PA194&dq=S.46368&source=web&ots=CZivLuIVkQ&sig=JQbIrT0zoON5wZ6eKD5zhOeVN2k&hl=en&sa=X&oi=book_result&resnum=1&ct=result#PPA63,M1p Appendix A p. 63] ]
*H2S - British ground mapping radar to see target at night and through cloud cover
*H2X - American ground mapping radar, development of British H2S
*Himmelbett - German controlled night fighter method
*Hohentwiel - FuG 200, German UHF airborne radar optimized for maritime (anti-ship) use
Huff-Duff- Allied HF/DF High Frequency Direction Finding
*Jay beams - were introduced partly as a deception to help to confuse the Germans over the use of GEE. It was nevertheless a useful as a homing beacon. A number of transmitters, from
Lossiemouthto Manston in Kent transmitted on slightly different frequencies transmitted a narrow beam across the North Sea using a S.B.A. 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 done 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.

Kammhuber Line, British name for the German "Himmelbett" radar controlled air defence system
Operational researchamong other it involved the statistical analysis of a anomalies, some caused by the use of previously unknown German electronic equipment or tactics based on the equipment and for example lead to the development of the Bomber Stream.
