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
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
