A small glossary for you Mark M-L:
CH: Chain Home, the name for the network of radars used in WWII on the
English coast.
IFF: identification friend or foe, now called SSR or secondary
surveillance radar in which the aircraft uses a transponder to reply to
certain sorts of radar signal and provide information. In war time it
is coded and identifies a friend; in peacetime it merely identifies
different traffic in the air and gives its flight level or altitude.
RDF: radio direction-finding, as opposed to ranging.
AI: air-intercept radar.
TX: transmitter station.
GEE and OBOE were homing signals to assist with navigation for bombers.
H2S: a model of radar that was first used in Lancasters and other
bombers (and night fighters I think), but a derivation of which was
still used in Cold War bomber, the Vulcan.
That's all I (think I) know ;-) They're all abbreviations, rather than
acronyms like RADAR.
