[Milsurplus] Radar

[C.Whitaker]

de WB2CPN
Radio Direction and Range.
The Brits did the Magnetron,
The Luftwaffe did the first radar station,
for the German Navy, it's said.  But they
did place Freya radar all up and down
the French and Dutch coasts for themselves..
Mass Inst of Tech (MIT) did the best
series of books on the subject.  They explain
how US got credit for Watson-Watt work.
RDF was a loop antenna, or a pair of dipoles.
