[Milsurplus] Radar

[Jack Antonio]

When did the term "radar" come into general usage?

I was just watching a TV series (Foyle's War) and
an episode plot line revolved around a Chain Home
station. The term RDF was mentioned, but was generally
referred to during the episode as radar. The time frame
of the episode was August 1940.

I was thinking the term came into usage a bit later.

I wouldn't be surprised if historical accuracy was
sacrificed to make the show a bit more understandable,
but am wondering if in fact it was or was not accurate.
