June 3, 1945
PFC Carl A. Lester, son of Mr. and Mrs. Ancil
Lester of Reliance, is one of the few men in the
service working on the new device that has just
been made public by the Army and Navy. Lester
was inducted from Lyman County Nov. 20th of last
year and since then has been located at Drew
Field, Tampa, Fla., where he but recently
received his diploma in Radar work.
Until about a month ago,
nobody in the army of navy has talked about the
radar. So secret has this amazing device been
that the word radar itself is almost unknown
outside the services, and not very well in them,
according to a British scientist.
Radar is a coined word
meaning radio-detecting-and-ranging. It
describes a devise operated by radio which not
only detects distant objects, but determines the
range and the distance to them. It is being
developed in this country and Great Britain.
A radar, said one
enthusiastic navy man, can pick up a tomato can
floating on the surface of the ocean 100 mils
away, and give you the distance within a couple
of inches.
Radar is one of the marvels
made possible by the electro tube. Its principal
has been known to physicists for many years ...
the focusing of high frequency radio waves into
beams which are reflected when they strike an
interrupting surface ... but war spurned its
development.
This beam of radio waves
traveling at a speed of 186,000 miles per second
scans the sky and sea to warn of the approach of
the enemy on many fronts. It provides data for
anti-aircraft guns. Fog, storm or darkness do
not blind it. It is as valuable on offense as on
defense.
